I had read that about the KM-5, that is produces erect stalks, sounds like a Fe'i, but the question should be why is that a problem? Does it cause the plant to be vunerable to winds? Its other contributions, nematode and disease resistance, are more important as the problems can be outcrossed, leaving the disease resistance.
Breeding diploids with tetraploids has its advantages but if more than two Bs, or adding up to more than two Bs, the naviruses will present destroying the prodogy or carrying the virus forward.
The progenators I use have very little Bs in them, and the most in a cross is one. I also am trying new wild musa as male prodgenators.
