Sorghum is the important cereal crop around the world and hence understanding and utilizing the genetic variation in sorghum accessions are essential for improving the crop. A good understanding of genetic variability among the accessions will enable precision breeding. So profiling the genetic diversity of sorghum is imminent. The D2 statistics was applied to assess the diversity among 228 genotypes of sorghum. The analysis of variance revealed significant differences among the genotypes for all the characters under study. The genotypes were grouped into 22 clusters, where cluster I comprised maximum of 115 genotypes followed by cluster II with 45 genotypes each. Inter-cluster distance was maximum between the clusters III and XXI followed by XIII and XXI with 33.50 and 33.26 each which indicated that genotypes included in these clusters may give heterotic response and thus better segregants. Regarding genetic divergence of the genotypes, panicle weight contributed major share followed by primaries per panicle with 25.64% and 22.92% each, these traits can be utilized for future crop improvement programme.
