Abstract

Genetic divergence of 35 sorghum (Sorghum bicolor L.) genotypes was estimated using D2 and principal component analysis for nine characters. The genotypes under study were grouped into 4 clusters. The cluster I contained the maximum number of genotype and the cluster III contained the minimum. The inter cluster distance in most of the cases were higher than the intra cluster distance indicating wider genetic diversity among the genotypes of different groups. The highest inter cluster distance between cluster III and IV followed by between III and V showing wide diversity among the groups.. The highest intra-cluster distance was observed in cluster IV and lowest in cluster II. Days to maturity, number of tiller/plant and 1000 grain weight showed maximum contribution towards total divergence among the genotypes.
