This study evaluated genetic diversity of Shandong C. Mollissima by means of 29 SSR loci. The aim of the study is to reveal genetic diversity of Shandong C. Mollissima. 29 pairs SSR loci of the distribution of Shannon - weaver index is 1. 272 0-2. 950 0 and the distribution of Simpson index is 0. 551 7~0. 940 9. This indicated that the Shandong C. Mollissima has abundant genetic diversity.
