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.

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


URL=https://www.casimages.com/i/200216055129990033.jpg.html][/url]


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

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".
