Tetsukabuto croce

Adaptation Projects Cucurbits
1

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

e]

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.

Exemple of crossbreeding between blue kury and tetsukabuto
