Pepo x maxima???
« on: 2020-03-02, 02:26:02 PM »
Hello,
Two plants stranger have growing in my garden!
The leaf are deformed.
What about is it?
This is an interspecific pepo x maxima?
Thank you! :)

Deformed leaves are more likely to be a sign of a virus disease. 

What makes you suspect that it might be an interspecies hybrid?  I am not aware that pepo does cross with maxima, but I am sure it might have happened sometime.  Did you try to cross pepo with maxima and got these as a result?

I test to hybrided a male flower of the plant (photo above) with a maxima.
Later i will sow the seed hybrid and i will see if the new plant are deformed!
the pistil of the male flower has a form of bowl a normal pistil is lengthen.

The plant has make twin male flower i never see this phenomene on a maxima but i see this phenomene on a pepo.One plant was germinate with one cotyledon.
See the first figure on the photo
The photo came on https://www.frontiersin.org/articles/10.3389/fpls.2018.01049/full

That is interesting Adrian,  I certainly have never seen a twin flower on a maxima either, but very common with c pepo.  Following with interest.

The plant at middle is the hybrid between one maxima and my maxima with gene pepo

One seed has germinate in my maxima with gene pepo f2 and the plant is not very vigorous. Little cotyledon, little leaf.

And the,big plant is a f2 maxima pure.

This season i will played with the zuchini black beauty pepo.
As black beauty is very precocious (50 days) I will try a few crossbreading.
For exemple black beauty x a f2 of justynka f1
 Or black beauty x ( justynka f1 x green hokaido.
I will try as well to hybrided black beauty with my moschata.
And maybe get a f2 maxima or moschata not runner.

I would like to create an hybrid pepo x maxima and a pepo x moschata for a best precocity. The pepo black beauty take 50 days.
My objectif is to make 2 haverest per year.
And have a plant tolerent at the court day for a possible third grow  at home the winter.

What is the best sense for the crossbreading? Pepo x maxima or maxima x pepo? Pepo x moschata or moschata x pepo?
The both sens pepo x maxima and pepo x moschata are more fast but the seed are viable?

I have attached my notes from some years ago about how likely squash are to cross between species.... Argyrosperma/mixta is a useful bridge between species.

I will compare the apical meristhem of a zucchini pepo and a squash maxima.
The zucchini have a less important cellular elongation than a squash i search the influence in the capacity to fructify or make male flower and of repair after an attack for exemple slug. Or difficult conditions.
