Abstract: 15 accessions from 3 kinds of germplasm were used to analyse the genetic diversity and to carry out cluster analysis by means of RAPD in Ardisia crenata Sims. 17 random primers, which were selected out of 200 random primers, generated 247 bands, and 92.71% of them were polymorphic. The result of cluster analysis showed that there were significant differences among the 3 kinds, which accorded with the result obtained from morphological classification.
