In present investigation 150 sorghum germplasm lines were studied for two years. The findings exhibited high heritabilityin association with high genetic advance. During 2015-16,82 genotypes (maximum) were grouped in cluster I, followedby cluster IV and cluster II with 22 and 19 genotypes, respectively, and cluster III having 11 genotypes, cluster VII havingnine genotypes only, cluster X consisted of three genotypes, while V, VI, VIII and IX clusters remain confined to singlegenotype. The cluster distances ranged from 16.98 to 84.52 (within the clusters) and 40.65 to 73.37 (between clusters).Similarly, for 2016-17 are grouped into different clusters revealed that the highest number of genotypes (96) were confinedto cluster I, followed by cluster IV, cluster II, cluster V, cluster III and cluster VI with 18, 17, 10, 8 and 1 genotype(s),respectively. The cluster distances ranged from 29.30 to 76,38 (within the clusters) and 0.00 to 71.11 (between clusters).Further for pooled data sorghum genotypes are grouped in to different clusters indicated that the 82genotypes (maximum)were associated with cluster I, followed by cluster IV, cluster III, cluster II, cluster VIII and cluster V with 19, 18, 15, 8and 4 genotypes, respectively, cluster VI, cluster VII and cluster IX had only one genotype. The cluster distances rangedfrom 26.85 to 117.88 (within the clusters) and 65.87 to 117.88 (between clusters). The inter-cluster distances were morethan intra-cluster distances, which pointed towards wide genetic diversity among the genotypes of various clusters thanthose of same cluster.
