Abstract
This study aimed to estimate the genetic diversity among 94 mungbean genotypes using K-means cluster analysis. The studied genotypes were grouped into seven clusters. Cluster VII (3.57) showed maximum intra-cluster distance, while minimum distance was exhibited in cluster III (2.14). The highest inter-cluster distance was observed between cluster VI and VII (13.29) followed by clusters I and VII (12.96), clusters II and IV (12.71), clusters II and VI (12.58) and cluster IV and VII (11.97). Minimum Inter-cluster distance was observed between cluster III and V (3.09). Cluster mean for number of clusters per plant, number of pods per plant, biological yield per plant and seed yield per plant were recorded to be highest in cluster VII. The K-means clustering analysis revealed no relationship between geographic origin and genetic diversity. The Intra and inter cluster distance was adequate for the determining of diversity among the genotypes. The genotypes of clusters VI and cluster VII can be used as a parent in hybridization for obtaining heterotic response and better segregants in mungbean.
