Abstract:

In order to strengthen the mung bean germplasm collection, protection and research, to provide ideal parents for cultivating high yield and quality mung bean. Based on the data statistical analysis, principal component analysis and cluster analysis method, we studied the coefficient of variation, genetic diversity index and intervarietal genetic distance of 37 mung bean germplasm resources and their 11 phenotypic traits. The average coefficient of variation was 18.45%, and the average diversity index was 1.22. The additive contributing rate of the first eight principal components amounts to 94.78%, and according to the relativity, 8 major discriminating characteristics were selected to reflect the comprehensive economic character and quality character. According to the genetic distance, the 37 materials were divided into 5 groups. Each group had different characteristics and showed abundant genetic diversity. This results are beneficial for us to use various characters to evaluate mung bean and widen the range of selection for breeding parents.
