Pollination Problems

[Ki6bud]

Has anyone had this same issue? Both bloomed at the same time and the pollinia was fresh. This was attempted three times with the same results. Genetic issues?

Two Phalaenopsis plants "A" and "B"

Orchid "A" (Big Lip Hybrid)
1. Self-pollination "A" to "A" - successful
2. Pollinia from "B" to "A" - not successful

Orchid "B" (Non Hybrid)
1. Self-pollination "B" to "B" - successful
2. Pollinia from "A" to "B" - successful
