Here we save the hermaphrodites and cull the others as the hemaphrodites bear the fruit. The young plants will bloom and the hemaphrodite flowers have pollen...the others don't. Usually we plant 3 together in a mound and cut down 2 of the 3 leaving the healthiest hemaphrodite. Out of 8 seeds recently planted...7 were hemaphrodites. I think this is pretty standard for most papaya in production.
