Abstract: Random amplified polymorphic DNA (RAPD) analysis was done on 40 Pyrus cultivars. Based on the similar coefficient , the clustering analysis was done. The results showed that Pyrus communis L. originated in Europe could be distinctly distinguished from the other three species originated in China by RAPD technique. Three Chinese species were not clustered into different groups respectively , but there were different distance between any two acces-sions. It showed that RAPD technique could be used in the lassification and identification of Pyrus of species.

Key words: Pyrus, RAPD, Cultivar identification, Phylogenetic relationship
