Re: Hybrid Vigor
Beth,
Here is a goood case to support your theory. The Erb 806 was grown from a
Holland 879 which was pollenated by the Elsbree 720. The Erb 806 was an orange
fruit, good sized.. The male pollinator was the Elsbree 720, which was a Black
720 crossed with my Andersen 815 plant in 1998. At the time, we all had no clue
the ANdersen 815 would throw squash, but it did.
I am heading in this direction. Jim Kuzma grew the Erb 806, which was a nice
orange pumpkin, keep in mind, but since the grandfather (as you so called it)
was the Andersen 815, it threw squash in the second generation. The first
generation from the male pollen of the Andersen 815 was used to create the
Elsbree 720 and that pumpkin too was of good orange color. Comprendez?
