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, The botanical and biological characters of the 60 Phaseolus vulgaris varieties were measured.The range of the Oushi's distance among the varieties was 0.11~0.985, calculated by the normalization of standard derivation and our own computer program.The analysis on 10 enzyme systems was done and 25 locaties were obtained.The ratio of polymorphic loci was 0.16.The average genetic distance was 0.056 8.Based on the analysis of genetic relationship of the dendrogram, the 60 Phaseolus vulgaris varieties could be classified into two types, one for dwarf variety, and one for the vine and semi-wild varieties.By using the average genetic distance of Allozyme, the 60 varieties could be divided into 8 groups, 5 for vine, 2 for dwarf, and 2 for semi-wild variety. The genetic distance of vine variety was relatively far, suggesting its importance for storing germplasm resource as breeding materials.

Key words: Phaseolus vulgaris, germ plasm, morphology, allozyme
