You should check out polyploid mutations. There was/is some work done w varying food crops w/in the comm ag industry... apparently such variants can/do yield better and/or grow w strong stalks. This is all from memory from a few years ago, so...
Anyway, the handful of odd ball plants I've gotten like that didnt' do anything special... in fact they were slow to start & eventually reverted back to a "normal" growth pattern. Think a few tried w breeding but nothing has come from it...? At least hadn't heard of the Poly-Super plant as of yet...
