i BELIEVE THIS IS AN F1 CROSS OR IS THAT THE NEXT GENERATION. i AM LOOKING FOR THE GENETICS STUDIES OF THIS. i BELIEVE SCOTT HOLUB HAD A GREAT ARTICLE/WRITE UP ON THIS SEVERAL YEARS BACK BUT I CANT FIND IT. MIGHT HAVE BEEN IN THE PGVG NEWSLETTER. I APPRECIATE ANY HELP OR POINT ME IN THE RIGHT DIRECTION. I PRETTY MUCH HAVE THE EQUINE GENETICS DOWN OVER THE LAST 30 YEARS WITH OUT-CROSSES AND LINE-BREEDING ETC. PUMPKIN PLANTS AND SQUASH ARE A WHOLE DIFFERENT GAME. I BELIEVE IT WAS ABOUT A 25% CHANCE FOR COLOR BUT i CAN'T REMEMBER HOW IT PROGRESSES FROM F1 TO F2 TO F3 ETC. i KNOW THERE ARE A BUNCH OF SCIENTISTS AND PHD TYPES THAT ARE GROWERS. THANKS FOR ANY HELP.

I think this is the link to the Squash Growing forum BP Link and you'll wanna Site Search squashkin squ(u)mpkin ...go weigh back down to at least 2020...below the ones with pictures... ...and the guys in lab coats may be along shortly to just...talk with you, this time...eg

I posted my take on it under your post in "seed starting". Hopefully someone will resurrect Holub's article because it seems there's a lot of renewed interest in squash breeding, probably due to the success of this latest round of 1885.5 Werner genetics within the AG's.

I did not say the white coats would not have
a little ketchup on them. There you go, though---eg

thank you "pal2" I will look it up. SCIENTISTS AND PHD. nothing but respect for these growers, botanists, biologists.
AS FAR AS THE KETCHUP GOES, I SPILL IT ON THE COUNTER TOP, NAPKINS, FLOOR(THE DOGS HELP OUT THERE)
Wife does not allow me to eat in her car though.
I do hope the white coat experts respond. Big Pumpkins forum and conventions provides loads of information.In my pre-retirement job; I shared information at work on the Emerald Triangle in California; too which I was immediately questioned on how do you know so much about this. Interesting and complicated story related to airplane testing.

I had said, butt backspaced over it:
'Just grow green, cross it with green and keep on keepin' green;
Know what I mean, Jelly Bean???'
on your other inquiry because I was a bit perturbed at negative comments to a YouTube video that
I, myself appreciated very much and...Then, I popped over here and...
Well, that'd be my policy, to do as I said and I have the seeds to do it, from last year's auctions.
I might not be able to care about/produce HUUUUUGE green squash but I certainly take note of
'the darker, the better'. Such contrast, lol---eg
Good luck in your quest---eg---squest??? Baaa haaa haaa ...

It can be modeled with a punnett square, green is recessive. F1 is approximately 0% (unless there are squash genetics in the pumpkin, which isn't super unlikely), f2 is approximately 25%. If you select the green progeny, you will basically get close to 100% green, but in reality its more complicated than that because in my opinion it is a polygenic trait, meaning multiple genes are associated with the trait. This means a 2x2 punnett square is only a crude approximation, and a better understanding would probably require a 3x3+ punnett square, which have much more grey area than the simple 2x2.

My recommendation is, create multiple genetic lines, cross between them, don't keep selfing squash into oblivion. Selfing can be useful, but in my opinion unnecessary if you have more than one squash x ag cross. Crosses between these two seeds should behave similarly to a self.
