i was wondering wat people know about chilli genes like wat characteristics are dominent and recessive. also how would i go about selective breeding of say a hot chilli to make it hotter. woould i start with a hot chilli then take the hottest chilli of the bush (taste them to find hottest) n grow out al its seeds then take the hottest chilli from the f1 generation n keep goin, would self polination be important??? cheers

RE: Chilli genes

I don't know a lot about what traits are dominant and recessive.
Hot is dominant to non-hot.
Dwarf is generally recessive. There are more than one gene for dwarf. Perhaps some are donimant, I don't know.
The start you proposed would work probably. Selection in the F1 would not do much either way. Selection in the F2 and later would be more effective.
Some use what is called Single Seed Desent. With this method, you inbreed for a few generations before selecting. You grow many F2 plants, then grow one seedling from each of those and one from each of those for a few geneations. Then you compare the lines after they are each breeding true.
Self pollination woould be important. Peppers are generally self-p[ollinated, but you will want to decrease your chances of out-crosses, as you might loose years of selection by a chance outcross.
Myself, I find there are already plenty of very hot peppers. I am going for milder ones, and better peppers for bonsai.
