If you breed an ultra to an ultra, then you will get ultras. I believe you said yours was an ultramel. In that case, breeding an ultramel to a sunglow motley will give ultramels and amels both het for motley. Or breeding to a butter motley will give amels and ultramels het for motley and caramel.
Even if you kept breeding them to a pure corn, they are still technically hybrids. Now if after several generations, you could probably say they've been out-crossed enough that they're as pure as any other corn. But if you're set on breeding pure corns, then I would just buy another that is pure.I will most defnite mark the blizzard project as king hybrids. I wouldn't want to get any surprises, so I wouldn't drop any on others. So if I keep this strain going and keep breeding back to pure blizzards will I ever get pure corns again or will they always have some king in them. I plan to purchase a blizzard male at one of the many shows this year in Fl. I know its not liked by most but I really enjoy my jungle and plan to keep producing them. You know in the same since I didn't want to sell someone a snake calling it a jungle and it turns snow white as adult. So I guess what I will do is call the all white ones hybrids and the ones showing the color Jungles. Thanks for answering both questions for me.
