A new cytoplasmic male sterile line of Chinese cabbage with no yellowing at seedling stage, normal nectary, solid growth, easy transfer and stable fertility was bred for the first time in China. The effects of medium composition and culture conditions on isolated microspore culture of Chinese cabbage were studied. An ideal culture system was established and a large number of microspore regenerated plants were obtained. These DH plants are being used for new variety cultivation and molecular genetics research. Two markers linked to TuMV-C4 gene and five AFLP markers closely linked to TuMV-C 1 were found for the first time.
