Introgression of genic male sterile gene of Chinese cabbage into ovate ecotype Chinese cabbage variety

Based on the Multiple Allele Hypothesis of genic male sterility,the synthesis transferring method was used to transfer the gene of male sterility into the orbicular-ovate type Chinese cabbage variety '160',whose genotypes were msms by crossing,inbreeding,sibling and test crossing.New AB lines type I,new male sterile lines and their corresponding temporary maintainer lines of Chinese cabbage variety '160' were obtained from the transferred progenies of the Chinese cabbage variety '189'.
