I have propagated one of my F2 Basye's Amphidiploid seedlings with the intention of distributing it to other hybridizers who might like to do work with it. I will have plants ready to ship in another few weeks. Let me know (in comments or private email) if you would like to acquire this cultivar for breeding purposes. This is the one I am speaking of:
It sets seed readily with a wide range of pollens, propagates easily and is immune to Blackspot and Mildew. It does not repeat but has the genes for remontancy in it.
