Genetics & Breeding
Breeding a hybrid back to one of its parents to reinforce that parent's traits in the offspring.
A backcross (BX) is when a breeder crosses a hybrid back with one of its original parent plants (or a genetically similar individual) to strengthen specific desired traits. Repeated backcrossing — BX1, BX2, and so on — pushes the offspring closer to that parent's profile, which is how breeders preserve a beloved 'clone-only' mother in seed form. It's a core technique for stabilizing genetics.
