Abstract: Twenty-three accessions of Ardisia crenata Sims germplasm chosen randomly from different geographical locations at Mt.Gushan were used in the genetic diversity analysis by RAPD.The results showed that in the wild population,the number of effective alleles(Ne) was 1.4233,the Nei′s gene diversity(H) was 0.2524,the average number of alleles(Na) was 1.8060 and the Shannon′s index of diversity(I) was 0.3852.The data indicated that the genetic diversity was high in the wild population.Furthermore,their genetic proximity was high suggesting a highly stable heredity.
