This is interesting and new information to me. I had always thought it
didn't matter. So PBF might be more dictated by the pod parent; possibly
size, vigor, disease resistance, and branching might also tend that way?
Might explain why a 64" seedling of mine crossed onto the BB Shenanigan gave
BB babies. I was hoping for an average. Should have gone the other way, I
guess. I'm thinking the flower itself might be less sensitive to the
direction of the cross. Do you have any opinion on what characteristics
might be particularly direction-sensitive? (I'm sending this to iris-talk,
though I hope Bill Shear will answer, because I think a lot of us would like
to know. Anyone else have an opinion?)
