Thats a lot of tepins there, annuums and chinense usually have a hard time crossing with each other, baccatums will cross much better with annuums once crossed you can then cross with a chinense., some of the other wild birdeye types will cross with chiltepins, like C. chacoense and C. galapagoense. C. frutescens will cross with then too.
Since I live where there is a cold winter I just lay a drop cloth next to the plants and shake them real hard to get most of the pods and then hand pick any that are left on the plants except for the green ones which I will pull the plants and hang them upside down till the pods ripen or dry up, I put a drop cloth under the hanging plants and pick up the little pods that fall off.
Some times the bushes are still full of tiny pods so I lay the plants on news pappers or a drop cloth and spend the day picking pods when I'm setting back in a chair with a cold beer as it might take a few hours to get them all picked off.
I have one little tepin and a C. chacoense that will come back from seeds if I leave a few dried pods on the ground by the dead plants next spring I just word the podes into the soil and let nature take care of them.
This year I was going to grow some of my wild ones again, but The seeds were just to old as I had not kept back some fresh seeds so now I will have to ask around and or buy some rare varieties from some of the people here. Some of the rarer types take months to germinate even with fresh seeds so I will try and get some this summer and do a fall planting inside and by spring I should have a few of them up and growing.
Good luck with your grow and have fun picking all the pods.
