Re: Hybrid Vigor
Ray,
I for one am very interested in all the genetics ideas people have. I'd be
grateful if you'd post to the list.
That's a very interesting theory about the Checkons' pumpkins and hybrid
vigor and sterility.
Forgive me for not knowing the lineage of all these pumpkins off the top of
my head, but when you talk about "parents", what exactly are you looking at?
If you are talking about the (mother) plant and the (father) pollinator,
then I will be confused. If you are talking about one generation up, then
I'm okay, i.e., the (maternal) grandparents.
I thought the pollinator, which is the "father" most of us think about on
these pumpkins, has no genetic impact on the developing fruit - that the
purpose of the pollinator was to achieve maximal pollination, hence maximal
production of the growth hormones released by the developing seeds, but its
genetic traits won't show up until those seeds are grown.
My belief was that the "mother", the plant the fruit is growing on, provides
all the genetic material for that fruit, and so the genetic "mother" and
"father" would be the maternal grandparents. Please correct me if I'm
wrong.
So then, does your theory about nearly mutually exclusive genetics hold up
if you look at the "parents" of the 935 and 815 (did I get those right as
the female parents of the 1131 and 1190??)
Thanks,
Beth
