Hello this year i will growing tetsukabuto.
I would like to make a good croce.
I think at tetsukabuto x violina

What is your best croce with tetsukabuto.
Tetsukabuto is a male sterile?
Can i found character of maxima on my next generation?
I also have a packet of tetsukabuto I got for Christmas.
I will probably plant it with either or both Lofthouse buttercup (maxima) or Autumn's Choice in the F2 (moschata). I also have some tetsukabuto descended maximoss from Joseph Lofthouse. So I might plant all four things together or I may try to separate some of them for seed crops depending on what I have at planting time (~may 15th) in terms both of new seed and prepared ground.
I don't know how much maxima you will have in the F2 but it will be 75% moschata so any recessive maxima traits will be suppressed.
I think you are correct that they are male sterile in the F1.
Joseph may have gotten some restored fertility in the F2 when he was making his Maximoss.
I would like to found the character of futsu kurokawa on a butternut violina and if its possible keeping some characters of maxima.
The male sterile trait is easy to see. The male flowers shrivel up and fall off when they are still small.
The F2 segregated for normal looking male flowers.

Hi Adrian,
Does violino grow well for you? I have planted it in two seasons, and only gotten one fruit from it, but that fruit was good. I haven't tried crossing it with tetsukabuto from Joseph, but I could try this year. The seed he gave me, "Maximoss", fruits prolifically in my garden and does not suffer squash borer damage. However--I have not planted the offspring (F3) of the seed I saved from Maximoss plants I grew in 2018. I gave some of the seed to one person last spring, who told me he had zero germination from it, but he's an inexperienced gardener and I don't know if his results are meaningful. Haven't germ tested the seed yet.
From what I understand, you want to do a male (Tetsukabuto) x female (Violino)? I hesitate to try that because Violino sets fruit so sporadically, but it would be interesting to see the offspring.
As tetsukabuto product in theory not seed when he is autofeconded , i think to make the crossbreading in the other sens and take a male flower of violina.
Yes, having Violino pollen and Tetsukabuto mother plant is how I'd do it. Let us know how it works out!
Here i will put all my croce breeding with tetsukabuto for this season
( justynka f1 x green hokaido) x tetsukabuto

Justynka fruit salmon
Green hokaisdo green fruit
Later blu of hungary x tetsukabuto
Violino rugosa x tetsukabuto
I will create my interspecific cross maxima x moschata
I think at justynka f2 x violino rugosa or waltham. justynka f2 is very vigorous.
And ( justynka f1 x green hokkaido) x violino rugosa or waltham.
(Justynka f1 x green hokaido) is less vigorous the internode is more court than justynka f2 and she product a lot male flower.
I have a doubt. The fruit of tetsukabuto don't fat after more of one week After my crossbreeding.
Tetsukabuto is long to fat after the fecondation?
The male has been a maxima.
(Justynka f1 x green)
I have use two male flower.
What is the consequences to put differents maled pollens on one female flower?
The male pollen validate for start the developpement of the fruit is the most compatible or the most present in the taller quantity? or we could be have the caracter inhibited of each differents pollens males?
Sometimes fruits are slow to grow. Is it withering, or just sitting there looking fresh but small?
If it's withering, it's possible you used incompatible pollen. But normally using pollen from two male flowers is good; it takes about that much pollen to fully fertilize a female flower.
For the moment the fruit did not fat since more of one weeks ago.
But the peduncle lay allonged after the fecondation.
The fruit is not dry.
I will post a photo tomorrow
Finaly the fruit is fallen.

Tomorrow he will flowered 2 female flower of tetsukabuto and i have 1 male flower of blue of hungary wich will be flowered.
Today two female flowers with my plant of tetsukabuto.
I have make my crossbreeding tetsukabuto with blu of hungary for the first.
And i have let the choice of the bees to chose the pollen for fecondated the second female flower.
I like the surprise!
I don't think it is unusual for a first fruit to be aborted - the plant is aiming for "early fruit" but also "mature enough to form a fruit successfully" and the result is the first one often doesn't make it, in my experience, because really, the plant needed to be just that little bit more robust first. Hopefully there will be more and they will "do".
The fruit fecondated with blu of hungary begin to get fat.
The fruit begin fat

for my next hybrid i will try violino x blue of hungary
The male pollen of blue of hungary is very good.
Weeded my little squash patch today. 15 or so Lofthouse buttercup, three tetsukabuto F1, and 5 of the G2 of Autumn's choice a colorful moschata but the G2 is probably crossed with Lofthouse and Mike's grex though there was a tiny bit of Rancho Marquez pollen out there. So a hybrid(s) of a hybrid to make a new hybrid!
William, "little" is relative.
Wow you have a lot of space!
Yes, but less of it is squash filled than most recent years. So it is relatively less squash. Thus a little squash garden. I should take a photo from up on the hill . Total is maybe 3/4 acre this year but I have six tomato patches 150 feet from each other this year. Only three squash patches (some in combo with tomatoes). This one, a moschata patch that isn't doing well behind it, and a pepo patch for Josephs strain of crookneck. I thought I would plant more squash but it didn't happen and I am glad because I am still working on weeding the corn at least once. The corn is ~19 rows, each about 70 feet long. Wish it was tomatoes not corn!
Edit: added photo from a bit up the hill.
It's a beautiful land!
The compatibility of the pollen could play on the size of the fruit?
I think so, I tend to get good pollination on squashes. However, less pollinated seeds probably means a smaller squash. Within genetic limits for variety on squash size. However in 2017 I planted a much larger squash patch and the bulk of it was from seed from one large maxima grown in 2016. So it's possibe for me with just seed from one squash to plant a huge area!
Second fruit of tetsukabuto fallen
Weight: 0,2kg 0,441lbs.

with a male pollen of maxima blu of hungary.
The pollen was validated for the fecondation, the fruit has fat and have stopped is developpement and the pedoncle is becam yellow.
The fruit have the form of green delicious.
Tomorrow i did my crossbreeding violino rugosa x tetsukabuto.
A miss of boron and potasium in the ground could did fallen the fruit fecondated?
The fecodation violino rugosa x tetsukabuto is validate, the fruit gain in weight.
Hi Adrian,
How's it going with the fruit set?
We're getting lots and lots of moschata fruit right now around here. Possible maximoss too but I usually can't see them amid the green leaves of the squash patch until they mature. It has been very hot, above 90F/32C every day and rarely getting below 75F/24C at night. Less rain than normal, too. The squash like it.
Hello Kim K,
The fruit set is good and the fruit has a good size, i don't know how the seeds will be formed and if they will be able to germinate for tetsukabuto.The first fruits are matured and the plants start again to branch out with of new fruits.
https://www.casimages.com/i/200721020356522467.jpg.html](https://nsa40.casimages.com/img/2020/07/21/mini_200721020356522467.jpg)
Nice, glad to hear the fruit set is good. It's always exciting to have lots of squash!
What is the difference between this three fruits?
(https://nsa40.casimages.com/img/2020/10/27/mini_201027060146410797.jpg) (https://www.casimages.com/i/201027060146410797.jpg.html)
I will wait one month before to harvest the lasts fruits appeared mid september.
I don't know if the male fertility would restaurated if i sow the seeds of each fruits.
The possibles male pollinating was red kury, waltham, violino rugosa and blue of hungary.
My experience is that descendants of Tetsukabuto F1 crosses undergo normal segregation, and that male fertility is restored.
The descendants of Tetsukabuto f1 are generally vigorous?
Its just for have an idea with the density of the seedling.
Adrian,
I grew Tetsukabuto also this year with Lofthouse buttercup and the G2 descendents of Autumn's choice F1.
I've grown Joseph's Maximoss before and it produced but I think it wasn't great but then some portions of my squash patch tend to get ignored. I still have some seed I saved and I kind of let it cross freely with the Maxima grex so some genes could be floating around.
I have a lot of space though so what I will probably do is plant the remaining Maximoss seed. All or at least a great deal of the new Tetsukabuto seed. Then also will plant G3 of Autumn's choice descendants and probably some lofthouse buttercup just for eating unless I find a place to isolate the latter.
Wiliam,
If i have a crossbreeding with violino rugosa i think that he would increase the weight of the fruit and given an exceptional taste.
I don't unfortunaly grow the buttercup but i Think its great!
How day are required after thr fecondation of a fruit of tetsukabuto for have seed able to germinate.
60 days is low?
The rugosa gene of violino rugosa is dominant or recesiv, i would like transmited this gene!
Harvest of the lasts tetsukabutos but they are unfortunately take the freez at -3°C 26,6°F.
For sow the seeds recuperate of the tetsukabuto fruits,Must i take of precautions compared at a conventional seed?
I have open one fruit of tetsukabuto and i have found 30 seeds viable in the fruit.They are tall.
Sounds like good news!
(https://nsa40.casimages.com/img/2021/02/06/mini_210206051051266277.jpg) (https://www.casimages.com/i/210206051051266277.jpg.html)

Who is the parent?I am very curious.
I've been holding off on the Tetsukabuto F1 and focusing on other squashes. So I opened two. The first even though it stored nicely was not ripe enough and had no viable seed. The second had lots of viable seeds and was much riper.
Ten more to open.
Why a few seeds look like more flat after to have dried?

Why a few seeds look like more flat after to have dried?
Probably not as good as the plumper seeds. You could dissect one. Or just plant. I thought I was feeling some oddity in the seeds from mine. Such as partial fill. Sometimes such a seed might germinate into a seedling with odd Cotyledons but then develop normal true leaves. Squash seeds can vary a lot in thickness and still be viable.
I can try yo started their germination in of hot water before to put my seeds in the pot.I will use a potting soil very draining:a mix with coco peat potting soil with potting soil mychorize and cofee ground.
i think at an experience:
for this season i will put in the same square my tree tetqukabutos hybrids.
At left, tetsukabuto x n maxima: female allele:2/8 green delicious and 2/8 futsu kurokawa, male allele: 4/8 n maxima
at midle tetsukabuto 1/2 green delicious male allele 1/2 futsu kurokawa female allele
at right tetsukabuto x n moschata: female allele:2/8 green delicious and 2/8 futsu kurokawa, male allele: 4/8 n moschata
The tetsukabuto will have the two alleles with maxima and moschata
Mother allele 2/8 futsu kurokawa and 2/8 green delicious
male allele 1/8 futsu kurokawa and 1/8 green delicious and 2/8 n maxima or n moschata
The hybrids tetsukabuto x n moschata or n maxima will have
female allele:1/8 futsu kurokawa and 1/8 green delicious and 2/8 n maxima or n moschata
male allele:1/8 futsu kurokawa and 1/8 green delicious and 2/8 n maxima or n moschata
Second fruit opened ,i have found 13 seeds for a fruit appeard mid july and harvested mid october.I think that the parent is maxima ( red kuri).
Its nornal that the seeds floating after to be exit of the fruit?
Yes, floating is ok.
I have try to sow a few seeds for see if they are viable.
Temperature of germination:between 15 and 30°C
Potting soil:N=6 P=7 K=8 with mychorize.
Humidity:between 20 and 60%.
Ok i will try to sow a few seeds in a bottle that i have cut for increase my germination lucks.
The plastic of the bottle will did a little greenhouse effect and keeping more of humidity than a seedling in pot.
For not broken the germs i have put each seeds in a tea bag with coffee ground on.
She is alive!!!
Tetsukabuto x violino rugosa
The germ look like thin and sensitive, i have add a mulch for have a best humidity of potting soil and for moisten the shell of the seed for avoid that she stick at the cotyledons.I hope strengthen the germ!
Its a bad sign when the germ is long to exit of the seed?
A second seed of tetsukabuto x violino rugosa has germinate!
The germ look like more vigorous than the first seed.
I note that the seeds f2 of tetsukabuto are very long to germinate, the germ is exit but i don't see the cotyledons.
If they arrived to germinate, i think that they will be of beautifuls plants!
I have put my seeds under a growlight during 12h30 per day with a lightening of 4000k.
My potting soil be lightely compacted by drying.
The mulch was help to decompacted the potting soil.
The temperatur is between 15°C 59°F the night and 21°C 69,8°F the day toward a window.It may too cold!
Ok i will try a a different method of germination.
A seed of tetsukabuto x violino rugosa that i have put in greenhouse will germinate.
I will see if she is able to germinate with the natural light.
Thr big problem that i have see with the firsts seeds is that the germ has of difficulties to stretch.I will try to watered with a solution rich in auxin.water and sugar and the seeds of lentils and barley in germination.
I hope that an embryon rescue is not necessary.
For tetsukabuto x red kury, the seed is open and i see of cotyledons but i have not see of germ.He may exit more later.
I think that i have found the bests conditions for the best germination of my tetsukabutos F2.
I note that tetsukabuto x violino rugosa required a lot of heat for germinate.I have try a germination in my greenhouse under a wintering veil.I have measured the temperature under the wintering veil and she was between 3°C 37,4°F and 42°C 107,4°F and a humidity between 56 and 99%.The germ is more vigorous in greenhouse than in the house who i have mesured a temperatur between 15°C 59°F and 23°C 73,4°F with a humidity between 35 and 45%.
He has germinate!!!!
Tetsukabuto x violino rugosa
It look like more difficult for this plant.
Tetsukabuto x red kury
The seed has germinate without exit of root.
I think that she has did a root.
Tetsukabuto x violino rugosa and tetsukabuto x red kury!
Cool they look like very vigorous!
More vigorous that i hoped.
The roots exit of the pot.
.tetsukabuto
Tetsukabuto x violino rugosa
Tetsukabuto x red kury
If tetsukabuto x violino rugosa and tetsukabuto x red kury do male flowers and they are autofecondated the fruit will be able to gave viable seeds?
Or it better to crossed them again with tetsukabuto?
Can i have a best fertility if i crossed tetsukabuto x red kury with a different butternut?
Some of the [Tetsukabuo x other] plants may have normal male flowers, some might have male flowers that shrivel up without making pollen.
The heat and the cold periods and the high humidity rate can remove of genetics barrier?
When they germinate in the house i think the humidity rate is too low.
It worth it an hybrid ((Tetsukabuto x moschata)x(tetsukabuto x maxima))?Or bettert o autofecondated it?
tetsukabuto x red kury is able to receive of male polen of moschata?
Tetsukabuto x red kury is beautiful
Tetsukabuto x violino rugosa will grow
what is the best density? 1m2 or 1,5m2 per plant?
I plant squash 15 to 30 cm apart in rows separated by 3 meters, which is about 0.5 to 1.0 square meters per plant.
I have open the the 4th fruit of tetsukabuto!
The parent is (red kury x green hokaido) with small seeds.
He has 30 seeds viable. weight:600g
The seeds loik like full but very differents!
I have create a monster!
I have understand the better is to cross tetsukabuto x maxima with a moschata for have a great vigor.
If that is your intent, I'll be curious to hear of the result!
I think it is possible to have a plant more vigorous than tetsukabuto!
The seeds tetsukabuto x moschata have a germination very difficults.They accepted to germinate but the germs are extremely thin and the collar is small.The roots are above the potting soil, i have try to hillock them.It scary but they are largely alive! They are did a lot of roots.
You can see a photo
Seed of the third fruit
This seeds look like more flat but i think they have less inhibitor of germination than the seeds of the second fruit the most full.
I have try to sow one seed of tetsukabuto x (red kury x green hokaido) and she germinate.Its the seeds of the 4th fruit.
Tetsukabuto x (red kury x green kokaido) and tetsukabo x violino rugosa.
A lot of vigor
Today, i have put the two firsts plants in full ground.
I will did a lot of experiences.
I have choose a density of 1,50 m2 per plant for have the maximum of fruits for the same plant.I will try a lot of differents combinaisons.
Its possible to have an hybrid able to did male flowers with the combinaison ((tetsukabuto x moschata)x(tetsukabuto x maxima))?
Photo of the plants in full ground
I don't see male flower on this plant but i see two fruits one at each internode.
Plant of the third fruit
I note that moschamax is less vigorous than maximoss but he look like more resistant.
Just planted a few seeds of the F2 in the backyard along with Moschatas. I think I have a few seeds left of the F1 but they are hard to find in my bins of seed.
4 th plant :tetsukabuto x red kury
The leafs are dark and he look like at a moschata!
First female flower for tetsukabuto x blue of hungary kury! The alone male polinisator available tomorow is blue of hungary.
finaly the flower was non open.
maybe a next time when the plant will be more strong!
They are beautiful
I hope they not male steriles.
The second plant has a small nitrogen deficiency?
The fertilisation for this plant was a potting soil N=6 P=7 K=8 with mychorize the 10th may.I have put a granule fertiliser N=4 P=3 K=5 yesterday with vermicompost.
Its low as fertilisation?
The firsts fruits appeard on each plant.
First fruit
Tetsukabutox butternut and tetsukabuto x violino rugosa
Heavy genetic?
What rate compatibility can i have if i try to hybrided cucirbita maxima with tetsukabuto x moschata?
Maxima x moschata =40%
Moschata x maxima =10%
First female flower open for tetsukabuto x violino rugosa the alone plant with male flower is for this moment blue of hungary. I think this genetic is not compatible.
With a parent too different the fruit accepted often to get fat but he can fall extremly easily.A fruir not totaly fecondated is tasty prepared as a zucchini.
As i had not moschata pollen i have put pollen of cucurbita maxima blue of hungary and pollen of cucurbita pepo black beauty for fecondate tetsukabuto x violino rugosa.
I hope nothing of this cross but it was the alones polens availables today.
The weather is humid today the fruit can accepted to get fat and fall later without viables seeds.
You can see the female flower
I'm scared that my plants did not male flowers.I will try to sow a butternut or a violino rugosa for the male flowers.
Ok im sur i think tetsukabuto x butternut is able to did male flowers viables!
He is the less vigorous plant of the experience.
If my planting scheme in the Moschata bed escaped the excessive cat modification I may have one Tetsukabuto F2 but it is very small if so. Then I may have two of the green fleshed, they have very mottled leaves if so.
Tomorow, first fecondation between
tetsukabuto x butternut and tetsukabuto x violino rugosa
I hope the weather will be not rainy for not have water in the flowers.
First male flower of tetsukabuto x violina
Unfortunately, the weather was rainy today and i have not see a lot of bees around the flowers.
I have tryed a manual polinisation with a brush.
What quantity of pollen is required for validated the polinisation?
How much fruits can i polinisated with one male flower?
I will see if the fruits are able to get fat.
As the weather was himid, the polen was stiky and i have see water in the male flower.
1 male flower for pilinisated 2 fruits its good?
Tetsukabuto x red kury will open a female flower tomorow.
The alone male available tomorow is a F2 of red kury x green hokaido.
Results: on 5 plants 1 for this moment has open a male flowers.
A second plant look like have viable male flowers!
The cross the most able to have male flowers looks the tetsukabutos crossed with moschata.
I note that the females flowers are open before the males flowers.
The alone plant to have open male flowers is the less vigorous of the 5 plants.
I was dont think to have so little male flowers for the second generation.
Tomorow fecondation of tetsukabuto x violino rugosa with butternut and tetsukabuto x red kury with a f2 of red kury x green kokaido.
This plant has stranger leafs
Impossible: tetsukabuto will open a male flower tomorow and he has a twin male flower.
I have empty a bucket with seeds of rye that i have stay take the rain.A few seeds has germinate.The rye contain auxin and he may stimulate the male flowers on tetsukabuto.
It is the good explication of this phenomene?
I will try a fecondation with tetsukabuto x violino rugosa the next flower is open in two days!
It normal rhat the plant continue to did fruits with 5 fruuts on the same plant?
I have put the male flower at the fridge in a water glass.
The male pollen of tetsukabuto is fertile?
The next polinisation is in two days with tetsukabuto x violino rugosa.
Tetsukabuto x red kury has open a male flower today and i have the male flower of tetsukabuto.
What is the better male flower for have the better cross with tetsukabuto x violino rugosa?
It worth it to use the pollen of this male flower of tetsukabuto?
Finaly the male flower of tetsukabuto has not a sufficient quantity of pollen for fecondated a fruit
The fruit of tetsukabuto x violino rugosa look get fat and he was hybrided with the variety tivano f1.
Someone know the variety tivano f1? She is proach of waltham? Someone know thr parents?
https://en.mt-shop.voltz-maraichage.com/organic-seeds/edible-squash-tivano-f1
The big difficulty for stabilisate an interspecific cross is the defiency in male flowers.Its difficult to have a male flower available the day of a female flower is open.
How much time can i keep a male flower viable at the fridge?
I was sur, tetsukabuto is able to open male flowers!
Second male flower of the season on this plant.
The female flower open today is tetsukabuto x(red kury x green hokaido)
Tomorow, a male flower of tetsukabuto x red kury and a female flower of tetsukabuto x violino rugosa will be open and at less than 1 meter of distance.I hope the weather will not too rainy for have the maximum of bees and the better quality of pollen.
I have see up to 4 bees in same time in the female flower of tetsukabuto x violino rugosa and two bees search pollen in the male flower of tetsukabuto x red kury!
Tomorow, tetsukabuto x violino rugosa open a male flower and tetsukabuto x (red kury x green hokaido) open a female flower.
I don't understand why no fruits arrived tovget fat, i see a lot of bees in the female flowers and i put pollen manualy.
The fruit started to get fat but the next fruit get fat more than the last fruit polinisated before.
I think the plant selected the fruit with the most of seeds.
Tetsukabuto x violino rugosa is a well idea but he gave a lot of fruits and he is may not able to did get fat many fruits in same time.
tomorow i will have female flower of tetsukabuto x violino rugosa and a male flower of butternut.
This butternut product a lot of anthocyan.
One fruit on tetsukabuto x violino rugosa look like to get fat officialy! It the most big of the plant.Unfortunately i don't know who is the parent.The two possible parents are butternut and tetsukabuto x butternut.I have did total trust at the bees!
They do a better work than the man.
Tomorow, autofecondation of tetsukabuto x violino rugosa.
One fruit is formed on tetsukabuto x ( red kury x green hokaido).I don't know if he will get fat.It thr fruit that i have polinisated with the male flower of tetsukabuto.She was so little pollen quantity that i scared that the polinisation is not complet.
Tetsukabuto will open the third male flower of the season tomorow.
Tetsukabuto x violino rugosa continue to did fruits its surprisingly the variety who did the most quantity of fruits and with the more big leafs of the 4 varieties of the experience.
@william what does give tetsukabuto x autumn choice?
Do you have a few news?
I have see up to 6 bees in the same female flower of tetsukabuto x violino rugosa.I think a plant liked by the bees is a plant able to gave good fruits.
Three varieties on the four has gave fruits
1: tetsukabuto x violino rugosa
2:tetsukabuto x (red kury x green hokaido)
3:tetsukabuto x red kury
I have understand why my plant of tetsukabuto has open male flowers!
I think it an hybrid between shishigatani x green delicious instead of futsu kurokawa x green delicious!
This flower is stranger.
She look at a male flower but i see a ovaris under the flower bud.
Tetsukabuto x blue of hungary???
Tetsukabuto x (red kury x green hokaido) someone know why the peduncle is so dark?
And tetsukabuto x violino rugosa
Tetsukabuto x violino rugosa on the plant with fig leafs!

I have the impression tetsukabuto x violino rugosa started to matured.
Harvest of the first fruit of tetsukabuto x red kury.I have found the fruit fallen.It was catastrophic:the pulpit was totaly
eaten by the slugs.
I have found a lot of seeds but very flat.
Strong ethylen odour.
i'm sur if he was not attacked he was be the better
He is matured
Perfect
I don't know if this fruit has viable seeds but i don't think he was autofecondated.
Each days or i have see male and female flowers on the same plant the fruits was avorted and they have also avorted when it had uniquely male flowers of moschata in the garden.
I hope really that the parent is an interspecific croce toward moschata. I have noted that moschamax has did more male flowers that maximoss.
Harvest of the fruit tetsukabuto x violino rugosa on the plant with fig leaf!
I don't understand, i have create my own interspecific cross?The seeds was came of a violino rugosa fruit or i have put maxima pollen (red kury) on the female flower but i have stay the flower open the next part of the day
Seed of rhe fruit tetsukabuto x violino rugosa with fig leafs i don't know what is the parent but the most probable is musquée du maroc.11seeds was harvested but they look very full.
Harvest of the fruit tetsukabuto x blue of hungary: i don't know who is the parent.This plant has product one fruit and the others are avorted.She has don't give males flowers.
I have found 40 seeds on the fruit.I can note that the fertility is increassed.
(http://opensourceplantbreeding.org/forum/index.php?action=dlattach;topic=363.0;attach=1621;image)
I think that this experience is a real sucess for this year!
Second harvest of the squashs!
Pulpit of tetsukabuto x red kury he has unfortunately no viable seeds.
Taste extremly sweet toward nutty.
I have found 1 seed in the fruit tetsukabuto x red kury who look viable!
To conclude i can note that tetsukabuto x red kury has not viables seeds and did very rare male flowers without pollen.
It so difficult to integrated precocious yellow at c moschata?
The fruits was extremly attacked by the slugs.
Tetsukabuto x blue of hungary have a lot of viables seeds and very rare male flowers with a normal pollen quantity.
The cross of tetsukabuto with a moschata restorated more easily the male fertility and the fruits have viables seeds.
They did a lot of male flowers after the fructification during the maturation of the fruit.
The weight of the most heavy fruits was of 2,6kg for tetsukabuto x blue of hungary and tetsukabuto x violina.
The max weight the last year was at 1,6kg for tetsukabuto.
Last squashs harvest of the season!
Do you think its a good idea to did a rootstock for melon with a tetsukabuto F2 or use a moschata F1is better?
I hesite between tetsukabuto x red kury and violino rugosa x butternut.
Pulpit and seeds of tetsukabuto x blue of hungary!
After a few days the seeds look unfortunately more flat.
Seeds of a second fruit of tetsukabuto x blue of hungary
I have open the fruit tetsukabuto x violino rugosa.
The seeds are big but a lot look flat
Weight: 2,6Kg
I hope that the parent is tetsukabuto x butternut possible?
have two parents possible tetsukabuto x butternut or violina x butternut.
Ok this year i will sow:
Violino rugosa x tetsukabuto: he was extremly late the last year and i will grow this in better conditions.It late but if the season is good i'm sur the taste is wonderful.
Butternut x tetsukabuto more early, sweet and pepper taste.
(Violino rugosa x tetsukabuto) x (butternut x tetsukabuto) i think it will be more early with the caracteristics of violino rugosa.
(Blue of hungary x tetsukabuto) x unknow
I'm scared to lost the pretty taste of blue of hungary x tetsukabuto but i can have great surprises if he was cross with butternut x tetsukabuto or violino rugosa x tetsukabuto.I hope he was cross with pink,green or blue maxima.
[br
I will did of red kury x tetsukabuto a rootstock.

I think i will have very tasty fruits!
Cucurbita maxima or moschata? This plant look dark but the cotyledons look like at c maxima.
I have throw a lot of differents seeds here and probably seeds harvestee of fruits maximoss that i have lost the control of the polinisations.
(Blue of hungary x tetsukabuto)x unknow
At top tetsukabuto x butternut and down tetsukabuto x violino rugosa
The males polinisatores are panther f2 and violino rogosa x butternut f2
Someone has grow tetsukabuto and panther f1 together and she has give me a plant!
Probably panther f1 x tetsukabuto!
6 days later after the post of the 4th june
I will try to graft watermelon on the variety red kury x tetsukabuto! The watermelon variety used is able to do fruits above 10kg!
Whzt is your better rootstock for the watermelon?

3 fruits f2 of tetsukabuto toward moschata and 1 f3 of tetsukabuto toward maxima was appeard this year:
I hope they have viable seeds!
The parents was all f2 of violino rugosa x waltham for tetsukabuto f2 toward moschata and very probably baby violino rugosa as parent.
Second stape of the project:
Do you think that it possible to stabilisated tetsukabuto in op?
Or stabilisated a fruit who look like at one of theses photos at the post above?
I opened my Tetsukabuto x Lofthouse Buttercup that grew in the Maxima patch this year and one of my Tetsukabuto F1s which grew in the Moschata patch this year. Got some seed saved. Next year may be interesting in the Maxima and Moschata patches.
Very interesting William!
The last year i don't had viable seeds on the moschata patch.Just some seeds who has germinated when i have open the fruit on november and nothing at spring.I will keep in priority the seeds of violino rugosa x tetsukabuto who was crossed with a f2 of violino rugosa x waltham (baby violina).This f2 was very more vigorous and early than violino rugosa and he had keep the nutty taste of violina.(https://www.les-tomos.fr/download/file.php?id=44642)
For the patch maxima it was more easy.He look like more vigorous than moschata patch.The seeds F3 can germinated without help and the plants look almost restorated their male fertility.I used the parent blue of hungary and retrocrossed the parent f2 with blue of hungary.
I hope have viable seeds on the moschata patch this year.
I'm scared to lost lot of vigor if i autofecondated the tetsukabutos f3 but i think that it can appeard funny things!
I opened my first violino rugosa x tetsukabuto.
30 seeds look viable for a fruit with a weight of 500g.
The seeds look like more big than seeds of cucurbita moschata and very full.I hope that they will germinated.
Ready for a f3 generation!
The second fruit of violino rugosa x tetsukabuto weights 1,9kg.
The taste raw was very dry and very nutty.
I will mainly stabilisated violino rugosa x tetsukabuto and blue of hungary x tetsukabuto the next year.

(https://www.les-tomos.fr/download/file.php?id=45328)
waltham x tetsukabuto is defitively a not viable cross.the seeds on the second fruit was all flats.
However with violina x tetsukabuto the seeds look well full.
I think that the male fertility is really restorated at the third generation.
At the second generation the plants opened a male flower at same time that the female flower.
1 male flower / 1 fruit at the second generation.
I've been frustrated with Blue Hubbard melons, where the early season flowers all seemed to be male. I could have had fruit sooner if early flowers had been a mix of male and female.
Cathy A the males flowers at the started of the season is normal.
Its more normal that this photo.
Male flowers at started are importants for habits bees to visits the flowers.
(https://opensourceplantbreeding.org/forum/index.php?action=dlattach;attach=1337;image)
The first seed of the season started to germinated it is about a seed of (violina x waltham)f2 x (violina x tetsukabuto).
Very curious to see what it can give.
Firsts seeds in germination!
Unfortunately some seeds are some difficulties to germinated.
Its normal that some plants give a lot of secondary roots and that the main root dryed?
Firsts squashs
I hope that they will give male flowers this year!

Its above my hopes!
They grow very fast
Very vigorous
I think that they will given very interesting fruits!
Difference between violina x tetsukabuto right and small violina x (violina x tetsukabuto) left.
I will cross this year tetsukabuto f2 with the f3 generation!
Small violina is a f2 of violina x waltham selected for have fruits of 2 kg with thr carachteristics of a violina.
On the second photo the plant has strangers leafs.
What fertiliser do you use for yours squashs?
I have used a potting soil with fertiliser NPK 15-15-15 in planter of 2L but after 2 leafs stage after cotyledons the leafs passt at the yellow? My potting soil is too poor or the nitrogen is not assimilatenable?
Nice to see squash plants. I've got a little time before I should plant mine.
I don't have any fertilizer suggestions because the only one I've ever used is manure, or rarely manure tea. But that's much easier for me to get being on a farm.

Blue of hungary x ( blue of hungary x tetsukabuto) one plant and two plants of
unknow x (blue of hungary x (blue of hungary x tetsukabuto)) around.
((Violina x waltham) f2) x (violina x tetsukabuto) has a very low vigor but if isn' eat by slugs he can growed.
Do you think that i can crossed blue of hungary with
(Violina x waltham) f2) x (violina x tetsukabuto) or
small violina x (violina x tetsukabuto)? I want created my own interspecific cross.
If a so cross can arrived it will be very crazy but its not my main objective.
My main objective now is to assembly the nutty taste of violino rugosa and the sugar rate of futsu kurokawa , the low vegetative t° of green delicious and the earliness of waltham in one variety.
I think that this generation will be very funny

Oh dang, those stems are aggressively fuzzy. Picture 5 is a plant that tells you very pointedly that it doesn't want to be touched or nibbled.
I'm going to be trying to do a direct moschata x maxima cross this year, trying to cross pollen from a Rampicante/Tromboncino/Zuchetta into a Gold Nugget maxima as the mother. I'm probably most curious to see how the long, curling neck interacts with the bulb-shape of the gold nugget in subsequent generations.
Hi Mica Winnower,
This picture is less fuzzy.
I selected a fruit with a shape ribbed and round.
Make a direct cross moschata x maxima is a good idea.Impatient to see the result between trombinonco and gold nuggets.
Unfortunately the probability that the cross took is low.
The nexts generations can be funnys.The second generation of interspecific cross has often greats difficulties to germinated:you should remove the seed coat for improve the germination.
If i must make my own cross moschata x maxima i will use a parent moschata f2 between violino rugosa and waltham and a blue maxima or green.
Do you think that i can try to crossed "unknow x (blue of hungary x (blue of hungary x tetsukabuto))" with "violina x waltham f2" or "small violina x(violina x tetsukabuto)"?
Sorry, I think there was a small misunderstanding.
I meant 'fuzzy' as in 'pubescent'; covered in small prickly hairs. Strong defenses against pests.
I would say that you continuing to cross both moschata and maxima back into your lines is a good practice.
I feel like either of those potential crosses would be good. At this point, what you cross is based on your preferences. I'd personally go for the unknown-x(blue x(blue x tetsu)) crossed with the violina x(violina x tetsu). I'm excited to see the fruit of the unknown parentage.
Data from Joseph Lofthouse says there's roughly 40% success rate on the moschata x maxima cross. I have two gold nugget mother plants that I'll remove male flowers from, and manually pollinate any female flower with the tromboncino pollen. If I can get good viable seed in my first year I'll be impressed, but the odds are good enough that I want to try. Maybe I'll get lucky by accident! I trust my local pollinators.
We have a big slugs presure and not stabile weather at started of season.Have fuzzy plants is very important for my conditions.
I have tried a cross 2 years ago between
Delica hf1 (maxima) as male parent and waltham (moschata) as female but it was a miss.I will soon tried others interspecifics cross.
The probability is so different if i use maxima or moschata as female parent?
Warning some cross are little suitable.
Some of my crosses was give fruits with all of the flats seeds at the second generation.Some plants of second and third generation may have a difficult germination or a low vigor at started.
It is more safety to make many cross with differents parents for improve sucess.
Plants give male flowers with viable pollen at the third generation.
For get the more suitable combinaisons i have make two cross the first generation: violina x tetsukabuto and waltham x tetsukabuto.
Second generation i have grow violina x tetsukabuto and waltham x tetsukabuto with some plants of violina x waltham f2 around for get the most suitable parent for each cross.
Violina x tetsukabuto (picture 2) look like in better health!
Blueprint of the squash bed.
Around 1 plant m²
Those plants look very healthy indeed!
I must say that the distinctive white spots/chevrons on the leaves are quite attractive.
((Violina x waltham) f2) x (violina x tetsukabuto) give her first male flower.
A stranger thing the pollen ball is masqued by a petal.
Someone know if this pollen is viable?
I have also not seen that before. Strange things can emerge from interspecific hybrids even a few generations down the line. Could also just be a random mutation or unusual genetic expression.
Is it inhibiting the pollinators from getting access? Is it repeating on the other male flowers?
Others males flowers seem normals.
Some fruits are appeard
(https://www.les-tomos.fr/download/file.php?id=51204)
First fruit who will get flower tomorow
It is about small violina x (violina x tetsukabuto)
Others fruit: unknow x ((blue of hungary)xblue of hungary x tetsukabuto)
And a other violina x waltham f2
How many generations away from hybridization can you go in one direction before becoming less receptive to pollen from the other direction?
Say, for example; Will a moschata pollen have a more difficult time pollinating a hybrid that is 3/4 maxima than it would a plant that is 7/8 maxima. How distant can the relatedness get before it becomes hard to freely accept pollen from either parent species again?
I don't know.
I have noted that if the parent is too far the fruit of the F2 get fat without viable seeds.
After a extreme heatwave the weather is very rainy. So rainy that the females flowers are full of water at the end of the day.The polinisation is difficult this year.
I will see if something get fat.
This fruit is ribbed
It is about of ((violina x waltham)f2)xtetsukabuto
Ooh, very fun!
Do you remember what the parents of this plant were? Where did the ribs come from?
It is about of ((violina x waltham)f2) x (violina x tetsukabuto)
Ribs came mainly from of violina
Some pictures.
Fruits toward moschata are ribed.
Fruits toward maxima look like at buttercup
Other funny fruit ((violina x waltham) f2) x (violina x tetsukabuto)
It just stay to fecondated violina x tetsukabuto with one
Phenotype tetsukabuto F3
I don't know if the pollen viability of the tetsukabutos F3 is totally restorated but a lot of fruits have avorted after have started to get fat.Some fruits are fallen with a weight of 300g and probably more.
The fruit of the photo at the post above has also avorted but it was well formed.I yet see a lot of bees in the flowers.
Best of luck!
Hopefully you're able to get a good pollination on the F3 Tetsukabuto. This is good data for understanding how the generations from original cross affect the viability of the pollen, even once it is able to make pollen.
Some fruits seem viable.I don't know who are the males parents.I gave make totally trust at the bees this year.
Gotta trust that the bees know what they're doing. I love a surprise.
One fruit is appeard on the plant ((violina x waltham)f2) x (violina x tetsukabuto) its a great sucess.
That's a good looking fruit. It has tetsukabuto as a grandparent, was it able to produce good male flowers?
Do you remember what pollen was used to fertilize the fruit?
This plant well produce male flowers.
Unfortunately i don't know if the pollen is of good quality.
I was not here the pollinisation day.
The most probable are a other tetsukabuto F3 or waltham as male.
3 fruits was fallen with a weight > at 500g on this plant.
I well will see what happened if i sow again the seeds the next year.
Small update of the project violino rugosa x tetsukabuto f3!
3 fruits seems very cools
A beautiful fruit was found hiden hang at the tree.This project seem more and more cool.
Harvest of the firsts fruits
At left i think that the unknow parent is finaly buttercup.
Buttercup x (blue kury x (blue kury x tetsukabuto))
Ar right blue kury
At middle small violina x ( violina x tetsukabuto)
I have make totally trust at the bees this year but tetsukabuto maximoss was grow next to tetsukabuto moschamax.Bees have probably make some strangers mix of pollens this year.They all have able to give male flowers with pollen in in correct quantity.
I opened the fruit (violina x waltham)f2) x (violina x tetsukabuto)
The seeds seems very big.
I have tranferd-it the charasteristics of tetsukabuto in a violina.
The second objective transferd it the blue color of blue kury in a violina.Someone know if its possible?
One of my plant of Buttercup x (blue of hungary x (blue of hungary x tetsukabuto))seem stranger.I don't know if the pollen will be compatible with my moschamax plants.
Her internodes seem very shorts
The collar seem very thin
Two F2 between ((violino rugosa x waltham) F2) x (violino rugosa x tetsukabuto)
Those look good. In terms of fruit, the first picture looks more like a typical C.moschata, but the second picture just 'feels' a little bit more like the tetsukabuto ancestor than the first.
Has this generation been able to produce pollen?
How do you think you will move forward from here in your future plans for this line?
Yes they all produced pollen!
The plant of the second picture is the plant who producted the most male flowers.

Hi, building up landraces the way Joseph does, last winter I have bought 4 strains of Tetsukabuto and equivalent (Iron cup, Maukai, and Shiatsu), all looking really really similar to Tetsukabuto. I actually had no perticular intentions behind that, just willing to see how it will show up.
Nonetheless, I have separated my 10 plants of each in 2 places : 1 in my moschata patch, one in my maxima, all oriented long storage, under first year of heavy selection for germination and vegetation vigour at early stage, in order to go to direct sowing post crushing my winter cover crops during May.
So I'll have seeds of each, I can't tell who's the daddy, but if you want some let me know. Could upload pictures later.
Hi Thomas Pic,
Enjoy to see the expériences of others gardeners!
Grow tetsukabuto at the middle of a patch a is for me the better thatchou can do it.The tetsukabuto plant will automatically selected the mosts fertiles fruits (the best pollinisated and the most compatible parent).
The firsts years with thoses cross are often difficults.
Thanks Adrian!
Here is how these look like right now:
...
Sorry I can't find a way to insert a pic in here!?! Can someone help me?. You'll find a piccture of them down at the end of this post, with ficifolias and kiwanos around, as of today: https://goingtoseed.discourse.group/t/direct-seed-exchange-among-eu-members-2024-2025/3037/21?u=thomaspicard
I'll open them around the 1stvof April. If some wants randomly pollinated Tetsu squashes with either moschatas or maximas please let me know.
A old seed of 2022 has accepted to germinated.
Unfortunately the cotyledons stays yellow.
It seem good for you?
She is inder a growlight with spectrum of 6200kelvin and 17000 lux of light.
How can i help ed the cotyledons to take more green?
It seem in progress

Got those seeds out for about 2 weeks from those crazily long storage squashes!!! None of these was even slightly damaged after a 6-7 months storage.
So each of those tens of random crosses are in separate bags. Some are 3/4 maximas, others moschatas, and noted as such.. I'll do direct seeding of these shortly. Breeding strategy still to be defined.
Got seeds for people in Europe willing to work on that
Quote from: Thomas Pic on 2025-04-27, 08:07:51 AMGot seeds for people in Europe willing to work on that
And by "that" I think primarily about 2 different lines of thoughts:
- breeding for ultra long storage with excellent eating qualities (may it be in moschata or maxima)
- breeding for creating an intermediate form, may it be a bridge between the 2 species.
Well,
Blue of hungary x tetsukabuto has germinated with sucess. As it will be almost male sterile can it accepted a pollen 3/4 moschata?
Some news of blue of hungary x tetsukabuto
Someone kow if she can received moschata pollen later?
My updates on GTS relative to differences of early growth in the following generation of a series of Tetsukabuto random crosses : https://goingtoseed.discourse.group/t/network-and-potentialization-of-a-squash-selection-loys-studies/3216/44?u=thomaspicard
After nearly 2 months of growth I confirm prior remarks on GTS: there is impressing difference of growth between crosses with Tetsukabuta: some being really small and slow others being big rapidly. Thus that doesn't match up with the size of the fruit in prior generation. It must have to do with the pollen donor, i.e. the other (unknown) parent.
Also: my 3/4 maxima are overall fast and big like maximas whereas my 3/4 moschatas are overall smaller and slightly slower growing like moschatas.
The seeds 3/4 moschata are often a very bad started and take a little of late comparated at the 3/4 maxima seeds.
I have noted for my F1 between violino rugosa x tetsukabuto that the weight was at 2,5kg.
A violino rugosa has a weight between 5 and 8kg.
The genetic of big fruits is problably recessiv for cucurbita moschata.

A stranger year for the squashs.
Drought and wind at the start of the season and too water in july.
The mosts bads varietys of the last year are a sucess and the better varietys of the last year are a miss.
Picture 1: blue kury, a grat miss the last year and a sucess this year.
Some plants dtarted to make appeards their firsts fruits but it seem a little late after september.
Picture 2: (violina x waltham) x (violina x tetsukabuto) F3. In spite of a vigorous grow the fécondation was very late.All the fruits aotofecondated was avorted.
A small fruit is appeard on Blue kury x tetsukabuto but the plant is died 20 days after the fécondation.
Picture 3: a plant or the fruits look lik at tetsukabuto
One fruit has accepted to get fat but it stay small.
I don't understand why all the seeds seem flats in rhe fruit (violina x waltham) x (violina x tetsukabuto) F3. It was yet picked when the plant was died.
I hope that the seeds of the lasts generations are again viables.
The last year was very stranger.
The F3 of (violina x waltham) x (violina x tetsukabuto) giving fruits with flat and steriles seeds and i was lost the most parts of the goods carachteristics of the parents.Nothing plant was synchrinised between male and female flowers.
I will grow this year the F2 and crossed them with some F3.
I note that eaven after 2 and 3 generations the male flowers of interspecific cross are less rich in pollen and more smalls.
Seedling of (violino rugosa x waltham) x (violino rugosa x tetsukabuto) F2 and F3
I don't understand why the root is above the cotylédons and the plant seem don't have collar.
Others plants seems good
Someone know why on some of my seeds the collar stay very thin and small? Its genetic or i commitee an error on my seedling method?
Tried a other seed of (violino rugosa x waltham)x(violino rugosa x tetsukabuto)F2
One of my F2 between blue kury x tetsukabuto seem stranger, he is seem have two heads have you already seeing that?
Firsts squashs of the season:
(Violino rugosa x waltham)x(violino rugosa x tetsukabuto) F2 at right and F3, they will be crossed together this year
Others sqhashs of the project blue kury x tetsukabuto
In front of the F2 with two shot of blue kury x tetsukabuto
Behind blue kury x (blue kury x tetsukabuto) but the collar seem dark green for a maxima genetic
My F2 between (violino rugosa x waltham) x (violino rugosa x tetsukabuto)F2 who has germinate in one month.I donnt know what he will given.Never seen a so stranger plant but she is alive.
This plant is issue of a blue kury seed, she seem have some moschata carachteristics

Its a great victory for the science, two wonderful fruits are appeards in (violina x waltham) x (violina x Tetsukabuto)F3 by autofecondation. The plant has a length of 7m. Unfortunately we are in october. Can i improvove the speed maturity?
The first frost is at normal time at the end of november.

Remove the smaller of the two fruits and any fertilized flowers or smaller fruits so all the plants energy goes into the biggest fruit.
When frost threatens cover most of plant with clear plastic held down in several places with shovels full of soil along the edge but mostly open to air. That can protect plant from being damaged by a hard frost so as to be able to take advantage of the warmer weather that sometimes follows the first frost.
Don't know if this works for squash, but with corn if the ears are too unripe to pick if you cut entire plant and bring it into an attached garage where it is warmer than outside but doesn't dry too fast the plant will use a good bit of the energy in the stalk to finish ripening the ears of corn.
Most squash fruits go through an after-ripening period during which the squash fruit transfers some nutrients to the squash seed and the seed continues to mature and get heavier. So when you pick the fruit, even if it looks immature, let it sit at room temperature a while. But examine it and turn the fruit daily and harvest the seed the instant you see any sign of mold.
Thank you Carol Deppe,
The fecondation of this cross is at normal time very capricious, i already seeing avorted fruits with a weight above of 500g in the lasts generations. They should have a weight up to 6kg if the season is good. Unfortunately ours summer was extrem and the plants has wait mid-september for started the fructification.
Can i also put mini greenhouse above the fruits?
If you have an ability to put a mini-greenhouse over the plant in the field, that's the best solution of all for giving the plant time to ripen the precious fruit. I would still remove all but the biggest fruit.
That's a very interesting cross.
If you are getting your F2, F3, etc by hand pollination, I would suggest you do the hand pollinations on the first or second female flower of the vine only, and use the pollen from three or more male flowers on every female flower. With such a cross, many of the pollen grains will have lethal chromosomal abnormalities that make the pollen unable to germinate, unable to grow its pollen tubes down the female style, or the pollen tubes can't recognize the signals the ova send out so grow all over the style instead of growing straight for the ova and merging with it. The ova is also going to be full of potentially lethal chromosomal incompatibilities but more of these are survivable through the Ova stage than through the pollen stage.
