Studies on Breeding for the Genetic Male Sterile Line in Greens Komatsuna

A directional transfer program was designed by using multiple allele inherited genetic male sterile line 06sx110 as the source of male sterility,and recurrent backcrossing was employed to transfer botanical traits,while the genotype was identified through test cross.Following this procedure,the male sterile gene was transferred to the target parent Y05 successfully.A new male sterile line GMS3,which is similar to Y05 on botanical traits with 100% male sterility and 100% male sterile plants,was bred.
