Hi Jim, Thank you for your response. I was obviously confused by this issue, but understand now what you are doing. I still don't comprehend the forces that are at work here. However, that is really immaterial and I am simply going to try it. I am mainly hybridizing gesneriads and I am looking for a way to quicker and more reliably stabilize the plants grown from seeds to consistently represent the qualities I found attractive in the best hybrids in the first place. I have been selfing the best plants back to itself for 3 generations, but still get too much variability in the offsprings, while species selfed back just about always give me the same plants back from seeds. So, thanks again for this new idea. Gene Sussli/San Francisco. --- firstname.lastname@example.org wrote: From: "J.E.

The microwaved pollen is surely dead and completely infertile. However, the dead pollen's surface proteins or polysaccharides are still there, and they are what one hopes will trigger the proper responses in the stigma to allow fertilization by other pollen, not microwaved, that is then applied to the stigma. You mix compatible but dead pollen with live pollen that would otherwise be rejected by the stigma. This way you get no unwanted hybrids mixed in with your seeds. Clear as mud?
