Hmm, why would that be? Is it that the potato leaf trait goes along with a bunch of other genetics, such that having potato leaf on both chromosomes would mean lower diversity because a whole bunch of genetics would also be the same on both chromosomes? I’m trying to cross Black Sean Man (BSM), a potato leafed sturdy fat stemmed fat fruited tomato, with various wilds. I was thinking in future generations, if my crosses are successful, to try to breed them as potato leafed varieties if I can, since you mentioned that possibility of advantages. But if that goes along with a bunch of other stuff that might be undesirable, maybe it’s not worth trying that… My idea was to try to cross the various crosses I hopefully get, like BSM x chmelewskii, BSM x peruvianum, BSM x cheesmaniae, BMS x galapagense, and some various BSM x (domestic x wilds). Like a new multispecies population. I’m also trying some other short fat big fruited early producing domestics with all these wild crosses. And, I want to try also crossing with chilense, but that should be hard. I have some BSM seedlings right now that I want to try making mentor grafts with to chilense, then use the BSM ‘pupil’ (or is it called ‘disciple’? I forget) as female to chilense pollen - a bit of a long shot but decades ago some Russians claimed to do this using peruvianum disciples with mentor grafts to domestic mentors, so I figure it’s worth trying, could be nice to have those chilense roots so don’t need to water them in long dry spells!
I’m glad to see some of my galapagnse and cheesmaniae starting to flower with exserted stigmas. I really look forward to seeing how crosses turn out with them! One galapagense has really nice flowers too, quite big!
