Default Re: pollination of wild species

A quick note on breeding: it does no good to try to derive triploids from wild species, because although they could be mostly sterile (if produced), they would not be parthenocarpic. It is a common misconception that bananas are parthenocarpic if they are triploid but this is not the case. They are two seperate systems within the plant. One way you can see this for yourself is by looking at the genomes of many edibles, there are diploids, triploids and tetraploids which are all parthenocarpic. In addition, sterility is not caused by ploidy alone in triploids, there are many different factors that determine sterility levels based on how they were originally selected, and even some triploids are highly fertile and some diploids are completely sterile.

So to make any use of M. basjoo in breeding (which does not even cross with wild diploids well at all, excepting M. itinerans), you would need to involve some fertile edible varieties.
