Abstract: The present investigation was carried out to study genetic divergence for fodder and grain yield in sorghum [Sorghum bicolor (L.) Moench] using torcher method. The genetic diversity analysis revealed that the formation of eight clusters suggested the presence of considerable genetic diversity among the 40 genotypes studied. The clustering pattern indicated that geographic diversity was not associated with genetic diversity. The analysis of per cent contribution of various characters towards the expression of total genetic divergence indicated that 1000-grain weight, protein content, panicle length, leaf: stem ratio, dry fodder yield per plant and grain yield per plant contributed maximum towards total genetic divergence. It was observed that 1000-grain weight (30.64 g), protein content (29.49 %), panicle length (12.82 cm), leaf: stem ratio (9.62), dry fodder yield per plant (7.82 g) and grain yield per plant (5.13 g) were the main contributors to the total divergence. Days to flowering (2.05 day), panicle width (1.28 cm) and leaf width (1.15 cm) shown small contribution. Maximum number of genotype observed in cluster I with 33 genotype, while other seven cluster observed with single genotype in each. Maximum cluster distance was found between cluster VI and cluster VIII.
