Abstract
This invention relates to a hybrid breeding technology for crop plants in the family Brassicaceae characterized in that F.sub.1 seed is produced by crossing the female parent of a male sterile line introduced self-incompatibility with the male parent of a self-incompatible line. By the breeding technology of this invention, selfed seeds contamination can be prevented in F.sub.1 breeding and F.sub.1 seed production of crop plants in the family Brassicaceae and, moreover, the cost of seed production can be reduced through an improved seed production efficiency.
