Most of wild species and some crops in Brassicaceae have self-incompatibility, which is a mechanism to prevent self-fertilization after self-pollen recognition by stigmas to avoid inbreeding depression and to maintain genetic variations in populations. Genetics and molecular biology of self-incompatibility have advanced by the studies mainly using Brassica crops, such as Brassica rapa and Brassica oleracea, and this biological trait is used for practical breeding of Brassica crops. In this chapter, the study of self-incompatibility in Brassicaceae species and its application to practical breeding program of Brassica crops will be reviewed and discussed.
