SUMMARY

The study was conducted on 25 forage sorghum genotypes (Sorghum bicolor L. Moench) were evaluated for their genetic diversity based on 18 morpho-biochemical characters. Genotypes grown in Ramndomized Block Design during kharif season to categorize them for fodder and quality traits. The mean squares were observed to be highly significant for all the 18 characters studied. This also indicated its suitability for further statistical analysis for all the character studied. The genotypes were grouped in to six clusters indicating high genetic divergence among them. Based on their intercluster distance and cluster mean for the various characters, it could be inferred that cluster I, followed by IV, II, and III were the most divergent from the other cluster. These genotypes can be
utilised for hybridization programmes. These traits viz. Green fodder yield, dry fodder yield, IVDMD and plant height upto base of flag leaf contributed highly towards the genetic divergence among genotypes studied.

Key words: Sorghum, variability, genetic divergence, inter-cluster distance, cluster mean
