Tetsukabuto croce

Hi,

I present you my project with tetsukabuto

The project is to combinated the taste of violino rogosa and the pulpit of tetsukabuto in a more early variety.

This project has giving exceptionnals things but he is very difficult to stabilisated

Some seeds have a lot of difficulties to germinated

For this year i will crossed F2 and F3 of (Violino rugosa x waltham) x (violino rugosa x tetsukabuto)

Hi Adrian, great to hear from you. I’ve got 2 questions :

  • what has been exceptional ?
  • why do you want stabilize this cross?
  • Or another way to say that : on which trait(s) do you want stabilize this project ?

I’m interested for 2 reasons:

  • I will shortly sow my F3s deriving from Tetsukabuto (some 62.5% moschata, others 62.5% maxima), which I’ve found disappointing in F2 (regarding vigor, storage and yields…)
  • trying to circumvent maxima disabilities in my ground (sandy, low ph, plants collapsing early, poor fruit quality…), I’m considering doing other interspecific crosses but with moschata as the mother plant - Tetsukabuto using a maxima as mother plant (Kurukawa n2, eq. Futsu Black) -, that to bring in maxima not only moschata’s nuclear DNA but also organelles, which seems to play a big role in moschata resilience and overall adaptability.

Until now my crosses haven’t been directional in the sense that I have no clue of parents : one share of my 2024 Tetsus were in my moschata patch, the other in my maxima patch, and reversely in 2025. I still have seeds of 2024 and 2025 fruits if interested.

* what has been exceptional ?

First exeptionnal thing: -a dry and very sweet pulpit in fruits up to 6kg.

  • Some plants are able to get up to 6 fruits by plants

* why do you want stabilize this cross?

Transfered it this taste and the carachteristics of pulpits at more early plants adapted at less propices climates.

A optional objective is to crossed one of thoses plants with a other maxima

You right F2 are very weak.

Eaven this year i note that some seeds have great difficulties to germinated.Some of my seed seem don’t have collar between the root and the cotyledons.

My observation:One generation can be very strong and the next generation not sufficiently vigorous for to be able to give a fruit

Small advice: If you want take a maxima in your cross, take a blue maxima

Thanks Adrian :folded_hands:

Why a blue maxima as pollen donor in an interspecific cross to come?

A blue maxima has a conservation near of a moschata and the carachteristics of tetsukabuto are dominants.

One of my seedling F2 between blue kury x tetsukabuto 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

Picture of my two shot squash, they can growed together or i must separated them? If don’t know if two plants are able to be synchronised

This seed don’t have collar and was sowed since one month, she started to emetted some roots.

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.

The two F3 and the F2 of (violino rugosa x tetsukabuto) x (violino rugosa) in full ground.
For the sélection conditions they must resisted at strongs rains and at chocking root with nights at 5°C 41°F.

The F3 in the second picture seem the most tolerant at my conditions.
The F3 seem globaly more strong than the F2.
I dont understand why the olds leafs are whitered.
