SUMMARY
The present investigation was carried out to assess genetic diversity in 30 sorghum genotypes based on nineteen agro-morphological and biochemical parameters during kharif2019. Analysis of variance showed highly significant variations for 19 quantitative parameters in the study. Further the genetic diversity was assessed with the help of D2 statistics and the genotypes under study were clustered into five distinct clusters. Among those clusters, Cluster-IV was the largest followed by Cluster-I and Cluster-III, each having 8, 7 and 6 genotypes, respectively. The maximum inter-cluster distance found between clusters IV and V (506.77) followed by distance between cluster III and IV (395.29). Genotypes mainly HJ 541, S 713, HJ 513, CSV 21F in these clusters are most suitable for their use as parents for development of dual purpose type genotypes in hybridization based breeding programme.
