Crossing a banana squash with a spherical-flat squash All F1 progeny had nearly spherical fruits Last year I have obtained 15 fruits of the F2 generation: 2banana shaped 10 spherical shaped 3 spherical-flat shaped Its seems regulate by a codominance of shape gene
Other advises? other experiments?

I agree....we need to know if those 15 fruit came from 15 plants, and the more plants grown the better. (100 would be ideal, but not many of us have infinite space) From what is there, I wouldn't think codominance...Id still stick with simple Mendelian..but need more info... Jim

Of course the sample is too small to have a clear understanding of the interaction. Its just a first observation of three differents phenotypes from this cross.
Only one fruit per plant.
May be more results at the end of this year, 46 seeds sowed in april and 42 have germinated...

Thanks for the pic Mayz....I love seeing segregation in a cross like this. Always cool to see how these crosses turn out. Jim

How do they taste? I always heard that Galeux d'Eysines was a beautiful and decorative spitter.

I have already grown the following cultivars blue banana, jumbo banana, gros jaune de paris, galeux d'eysines, rouge vif d'etampes, blue of hungaria and among them galeux d'eysines is most flavourfull and the one with the most colored flesh One problem it isn't good for long storage Here there's nearly no pest on Cucurbita maxima except powdery mildew at the end of the saison But Galeux d'Eysines is not hard shelled and its very easy to cut and peel it. Blue Banana is a very very very hard shelled and it becomes dangerous to cut it with a sharp knife. Attachments:

some news concerning the F2 progeny of the cross Pink jumbo banana x Galeux d'Eysines
mid may i have planted 37 F2 seedlings
Actually they are blossoming and i have counted 27 plants with a spherical ovary and 10 plants with a banana ovary.
Moreover 5 plants display yellow-green leaves (regulated by the recessive allele yg). One of both parents was probably heterozygous for this locus.

Were the F2 seeds all from the same fruit or from a mix of those different F1 fruits in the picture?

A pic of three immature fruits of the F2PJBxGE plants. The smallest fruit has a green peduncle that's a rare trait in this F2 progeny. Attachments:

Of no obvious relevance: two plants of my Minnie's Apache Hubbard are producing very large fruit, both splotchy pinky-green, one spherical, one banana. I may try selfing each to plant next year, to see what the progeny do, shape-wise.
