ok i'm confused--use pollen from two plants on a single flower, or pollen from plant A on one flower of plant B, and then pollen from plant C on another flower of plant B? sure, that would work. just tie little tags on each flower so you know what the stud was.
as for plant A and C on single flower of plant B--i suspect only one would pollinate it. but i'm lousy at plant genetics and ploidy-ness and all that good stuff.
