That tells me that they understand very well how to choose or develop the parent lines that will make a superior F1 hybrid.
I don't find it surprising that market F1's mostly come from in house breeding lines. I suspect a lot of work is needed to get the right parents that will combine in just the right way. Not that it couldn't happen with two random or select OP parents, but...
