Repeated selfing has no genetic consequence in self‐pollinated species (no inbreeding depression or loss of vigor following selfing). Similarly, self‐incompatibility does not occur. Because a self‐pollinated cultivar is generally one single genotype reproducing itself, breeding self‐pollinated species usually entails identifying one superior genotype (or a few) and multiplying it. Specific breeding methods commonly used for self‐pollinated species are pure line selection, and also pedigree breeding, bulk populations, and backcross breeding.
