There are 44 pages of Solanacae topics. So do we need more? Maybe not, but I'm starting a new one anyway. I've said before, elsewhere, that Chiltipines, wild peppers, are my favorite peppers. But they start blooming around time for first frost in my area, Kansas. Many year ago I crossed a Thai Hot with a Chiltipine and in the F1 I got a plant much like the Chiltipine parent, and the fruits were much like Chiltipines. But they started producing peppers by mid summer. I kept the F1 plants in pots and took them inside over winters. I kept those plants going for 5 years, before a power outage killed them. I never saved seeds from those plants.
So I'm going to cross Chiltipines with some early-blomimg pepper and cross them with Chiltipines. I'll be saving seeds and selecting mostly for early fruiting. And I think I'll be backcrossing 3 or 4 times to Chiltipines.
I bought some pepper plants last spring to cross with Chiltipines. But I didn't get my Chiltipine seeds planted until last week. But seedlings are up, in a 1 gallon pot. They, and the plants bought last spring, will be grown under lights in the basement this winter. I expect to fave F1 seeds to plant next summer. It is possible I'll have F2 seeds by summer. I don't know how well the plants will grow over the winter.
I have sowing the pepper that i am wintering in August the last year. And i have keep the soil dry during all the period of freez. I think that the drought and the cold (up to -5°C 23°F for the pepper) puting the solonacae in sleeping.
I think that the chilli pepper is more resistant at the freez that the pepper. You wintering your plants under a light?
