Abstract: In order to resolve the crosses breeding problem in utilizing hybrid vigor of savoy.A multiple allele inherited genetic male sterile line of Chinese cabbage was used as a source of male sterility,and methods of continuous backcrossing and identifying of the genotypes were applied to transfer the male sterile line of savoy.A new genetic male sterile line GMS_W with 100% male sterile plants and 100% male sterility was obtained,which was similar to the target line in horticultural characters.Two excellent hybridized combinations GMS_W×A2,GMS_W×A1 were selected,which was superior to CK in yield.Resolved the puzzle that breeding and utilization of the genetic male sterile line in savoy.
