Saving jungle peanut (Arachis hypogaea) seed from plants grown among perennial peanut (Arachis glabr

I'd like to grow a patch of different strains of jungle peanut and start saving seed from the ones that do well. Peanuts have a low out crossing rate, but I would save seed and hopefully find some new genetic combinations that do well in my area. I also grow a lot of perennial peanut as ground cover, though. It's all over my property. Perennial peanut grows edible flowers. If I get a cross between jungle peanuts and perennial peanut, and it grows nuts, how could I tell if they are safe to eat?
