Abstract: 【Objective】To analysis the genetic diversity of main cultivars mung bean and to provide excellent resources for mung bean breeding.【Methods】15 main agronomic characters and related yield factors of 113 main cultivars were analyzed by means of difference,diversity and cluster analysis.【Results】The agronomic characters of 113 varieties showed extensive genetic variation,in which the genetic diversity index of pod length was the highest,followed by the number of seeds per pod.The variation coefficient of disease resistance was the largest,followed by lodging resistance,and the number of seeds per pod was the smallest.113 mung bean varieties were divided into three groups by cluster analysis,and groupⅠcould be used as breeding materials for tall stalks and suitable for mechanical harvest.Although the yield of group Ⅱ was low,it could be used as breeding mater for short stalk and large grain,and group Ⅲ with high-yield,which could be used as breeding material for high yield and young stem color.【Conclusion】113 mung bean varieties contained rich genetic diversity and had excellent resources for breeding and mechanical production of high yield,tall culm,erect and grain size.

Key words: Mung bean varieties, Agronomic characters, Genetic diversity, Clustering analysis
