Title: Tetsukabuto croce
Post by: Adrian on 2020-03-18, 09:32:30 AM
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.

Post by: Adrian on 2020-05-10, 12:41:45 PM
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.
Title: Re: Tetsukabuto croce
Post by: Kim K. on 2020-05-11, 05:30:36 PM
Yes, having Violino pollen and Tetsukabuto mother plant is how I'd do it. Let us know how it works out!
Title: Re: Tetsukabuto croce
Post by: Adrian on 2020-05-31, 03:52:22 PM
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.



Title: Re: Tetsukabuto croce
Post by: Adrian on 2020-06-12, 09:31:03 AM
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?
Title: Re: Tetsukabuto croce
Post by: Kim K. on 2020-06-15, 09:36:42 AM
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.

Title: Re: Tetsukabuto croce
Post by: Adrian on 2020-06-15, 02:26:29 PM
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

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!
Title: Re: Tetsukabuto croce
Post by: Ferdzy on 2020-06-19, 08:47:15 AM
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".
Title: Re: Tetsukabuto croce

Post by: William Schlegel on 2020-06-27, 10:38:05 PM
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!
Title: Re: Tetsukabuto croce
Post by: Kim K. on 2020-07-02, 05:56:07 AM
William, "little" is relative.

Wow you have a lot of space!
Title: Re: Tetsukabuto croce
Post by: William Schlegel on 2020-07-02, 11:59:52 AM
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.
Title: Re: Tetsukabuto croce
Post by: Adrian on 2020-07-03, 01:22:24 AM
It's a beautiful land!
The compatibility of the pollen could play on the size of the fruit?
 
Title: Re: Tetsukabuto croce
Post by: William Schlegel on 2020-07-03, 08:26:03 AM
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!

Post by: Kim K. on 2020-08-13, 03:28:17 PM
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.

Title: Re: Tetsukabuto croce
Post by: Adrian on 2020-08-14, 06:27:24 AM
 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.

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.
Title: Re: Tetsukabuto croce
Post by: Joseph Lofthouse on 2020-10-28, 10:04:46 PM
My experience is that descendants of Tetsukabuto F1 crosses undergo normal segregation, and that male fertility is restored.
Title: Re: Tetsukabuto croce
Post by: Adrian on 2020-11-05, 02:59:48 PM
The descendants of Tetsukabuto f1 are generally vigorous?
Its just for have an idea with the density of the seedling.
Title: Re: Tetsukabuto croce
Post by: William Schlegel on 2020-11-08, 10:14:18 AM
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!

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.

Post by: William Schlegel on 2021-02-09, 05:40:06 PM
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 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

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.

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.

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%.

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?

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.

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.
Title: Re: Tetsukabuto croce
Post by: Adrian on 2021-06-30, 04:09:24 AM
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.

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.

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?

How much time can i keep a male flower viable at the fridge?

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.

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.

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.

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.
