Transfer of Genetic Male Sterile Line in Jiaozhou Chinese Cabbage

The hybrid Luxing 58 was used as a source of male sterility in order to get a new male sterile line,and solve the breeding problem of the multiple allele male sterile line with 100% male sterile plants in Chinese cabbage.Based on the heredity hypothesis of nucleolus compound allele of Chinese cabbage and the method of crossing,back crossing and selfing,a newAB line of Type1,and its corresponding temporary maintainer line of Jiaobai1 were obtained.A new male sterile line of Chinese cabbage nucleus gene with 100% nonplant rate and sterile degree was achieved by using the hybrid Luxing58.The directional transfer has been reached primarily,which will offer a convenient and rapid way for the researches on the transfer of genetic male sterile lines in Chinese cabbage.
