Successfully Transferring Genic Male Sterile Line to Ovate Ecotype Chinese Cabbage

Crossing,selfing and sibling were applied to transfer genic male sterility from AB21(AB line typeⅠ) to the male fertile line-Lu6-11(ovate ecotype)in accordance with Multiple Allele Hypothesis of Chinese cabbage in this paper.As a result the genic male sterile lines of ovate ecotype with 100% sterility were obtained.The genetic basis of the male sterile line was expanded,which widen the applied range of excellent genic male sterile gene.
