16 morphological traits of 21 mungbean varieties released in Jilin province were analyzed,the results showed that the growth habit,pod color,and seed color were monomorphic.The Shannon-Weaver′s information index of the higest yield per plant was 1.520 and the lowest pod shape was 0.736.All mungbean varieties were clustered into 6 groups.The relationship among all mungbean varieties was closer,so the diversity of parents should be increased in order to improve the population structure of mungbean varieties.
