Abstract: Sixty varieties of Phaseolus vulgaris were collected in this study, including 43 from Heilongjiang Province, 13 from The Center of International Agriculture Tropic and 4 from Poland, which were classified as 35 for vine, 12 for dwarf and 13 for semi-wild variety. This study was to analyze the genetic similarity and genetic distance in population and among populations of the 60 varieties and to draw the dendrogram of cluster analysis by using the markers of RAPD. Total 60 varieties in this study could be classified into 5 groups for vine population, 2 for dwarf population and 2 for semi-wild population based on the analysis of the dendrogram of cluster analysis for the markers of RAPD. It is of importance to collect Phaseolus vulgaris resources from home and abroad since Heilongjiang Province is the main area for breeding and cultivating Phaseolus vulgaris in China. The analysis for the markers of RAPD would be beneficial for investigating the genetic background of Phaseolus vulgaris in population and among populations and for identifying the inter-relationship in population. The present study would be valuable for preserving the germplasm and breeding good strains of Phaseolus vulgaris in Heilongjiang Province.

Key words: Phaseolus vulgaris, RAPD, genetic diversity
