That is an interesting issue others have noted periodically. From the beginning of importation of orchid species, it was obvious that some plants were markedly superior to others and some of the time it turned out decades later that the reason was polyploidy. We can’t expect a diploid species or hybrid to perhaps compete with polyploid versions. Yet, the award standards don’t care, so the polyploid plants usually win. Until there is a confirmed tetraploid kovachii, a triploid FS is a far as it can go. Someone is going to take a diploid cross using very good besseae and kovachii and then convert it chemically in the lab to produce full tetraploid plants. It will be very interesting what these look like. They could be better than our triploid versions.
