Abstract: In this paper, a DH population including 100 lines was used to construct a detailed genetic map to establish the identity of linkage groups corresponding to reference map of Brassica A genome. A set of SSR and STS markers provided anchors to previously published linkage maps for B. rapa and B. napus, and was used to designate linkage groups. Out of 230 SSR markers and 8 STS markers, 67 markers showed polymorphism between 2 parents and were analyzed in DH population. In addition, 448 previously mapped molecular markers，including 263 AFLP markers, 150 RAPD markers, 17 SSR markers, 3 SCAR markers, 14 isozyme markers and a morphological marker were integrated to a genetic map. This map contains 497 loci, and covered 1 086.7 cM with an average distance 2.19 cM. In this map, 36 markers previously published in reference map, including 34 SSR markers and 2 STS markers, were distributed in 10 linkage groups. Accordingly, these linkage groups were named following the A1~A10 of reference map, and were assigned to corresponding chromosomes.
