Abstract: The hybrid seed Luxing58 was used as a source of male sterility in order to solve the difficulty that some departments who were doing researches on the transfer of genetic male sterile lines in Chinese cabbage couldn′t get the genetic male sterile lines and the breeding problem of the multiple allele male sterile line which possessed 100% male sterile plants in Chinese cabbage.A new male sterile line,a new AB line Type1 and its corresponding temporary maintainer line of C₁-4 was obtained based on the heredity hypothesis of nucleolus compound allele of Chinese cabbage and the method of crossing,backcross,selfing.Compared with agronomic characters and the disease index of them and their parents.They were similar to C₁-4 in the disease index and the average values and variation coefficients of plant height,angular divergence,leaf length,leaf width,petiole length,leaf head height,diameter of leaf head,and to Luxing58 in gross weight of leaf head and net weight of leaf head.
