My tiny program has not experienced any pod or pollen infertility....but rather lacks focus on my part as my hybridizing for unusual forms gets the majority of my attention and has been more productive. I still set a few seeds every year on my cristate introductions as well as seedlings. AFTER THE RIOT is an easy pod setter and pollen is also good so it is an excellent parent if you are working with tets.
The pollen infertility that plagued the early dips was likely caused by a high degree of inbreeding that is necessary whenever you see anything "new" in form and there is nothing out there coming from different lines for outcrossing that can help with the fertility issues. I'm sure Maurice is better at explaining that. I was just lucky that Curt bloomed SIGOURNEY at about the same time that I had LITTLE BIG EARS appear in my garden so that we could do a trade. Crossing the two together helped produce fertile offspring.
