Hybrid breeding methods for crop plants in the family Brassicaceae.

摘要

This invention relates to a hybrid breeding technology for crop plants in the family Brassicaceae characterized in that F1 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 F1 breeding and F1 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.
