Abstract:A total of 207 pairs of SSR primers from 10 linkage groups of Brassica (A genome) were amplified on 9 Chinese cabbage varieties and 10 cabbage varieties. The result showed that 33 SSR markers were specific on Chinese cabbage compared with cabbage. These markers assigned on 10 different linkage groups of Chinese cabbage, in which 3 SSR markers on group A1, 4 SSR markers on group A2, 5 SSR markers on group A3, 2 SSR markers on group A4, 3 SSR markers on group A5, 4 SSR markers on group A6, 2 SSR markers on group A7, 1 SSR marker on group A8, 2 SSR markers on group A9 and 7 SSR markers on group A10. It laid a foundation to further identify cabbage-Chinese cabbage alien addition lines.
