I would like to try something like this. I have a few musa blue java bananas and given their level of hardiness, I think they could be good candidates for crossing with cold hardy wild species. But im curious, why would an ABB be better than an AB for crossing, given AB have the same gene count as the wild cold tolerant species and higher fertility? Helens hybrid after all is that of an AB and musa sikkemensis. Okay it's seeded, but the cross had just as high a chance of being seedless. Are the triploids hardier?
