I was trying to think of really strong growing diploids with purple foliage
bases. Two come to mind, but I'm not 100% certain that they re both
diploid (I suspect so though). These are 'Evolution' and 'President
Pilkington'. 'Evolution' produced fruit freely (apparently self
pollinating), which are big fat and full of seed. It might be an
interesting to add to a diploid PBF breeding program?
