SSR analysis on genetic diversity of 30 samples was carried out.Five primers selected from 36 primers were used to amplify 30 samples in this experiment,PCR products were separated by 6% polyacrylamide gel electrophoresis,silver staining and photographed.The results of SSR were analyzed by UPGMA clustering.The results showed that a total of 21 gene alleles were detected by 5 SSR primers.The number of alleles ranged from 2 to 5 with an average of 4.2.PIC range was 0.257-0.921,with an average of 0.543.The average coefficient of genetic similarity of SSR markers among materials was 0.432.Some of cabbage cultivars in the experiment were divided into four groups except cultivars which come from Japan.
