Study on synthesis model for breeding genic male sterile lines of Chinese cabbage

Abstrcat Synthesis model was applied to transfer genic male sterility from 3A(genic male sterile line) to sl05(selfing line) and to breed new male sterile lines in accordance with Multiple Allele Hypothesis of Chinese cabbage. The hereditary analysis showed that the genotype of sl05 is Ms~fMs~f. As a result, a series of new AB lines typeⅠand new temporary maintainer lines were obtained from self progenies of F_2 crossing 3A with sl05, and new genic male sterile lines with 100% sterility from crossing between the male sterile plants of new AB lines typeⅠand new temporary maintainer lines.
