Re: Precocious Genes
Nic, I've had a similar experience. I've seen
several young fruit a light shade of green which grew
up into very green squash. All yellow young fruit
I've seen have ended up medium to dark orange. The
white or cream young fruit I've seen have ended up
either light orange, or squmpkins such as Hera who
started out cream, turned salmon pink and then turn
70-80% blue-green.
I have yet to see a young green fruit with strips. So
I can't speak to that. All the above fruit I've grown
had nice orange flesh regardless of the outer skin
color.
It has been also my experience that approximately 1/2
the plants grown from a selfed pumpkin throw green
squash.
It appears to me that the green gene is recessive to
the orange gene and that most orange fruit have it
hidden in a chromosome somewhere.
Just my thoughts. Now that the biggest pumpkin ever
grown was a beautiful smooth orange color we all know
that orange pumpkins can be rather heavy too.
