The present study was carried out during kharif 2022-23 at Crop Research Centre-1, Department of Genetics and Plant Breeding, ITM University, Gwalior (M.P.) India. The study was carried out in randomized block design in three replications to evaluate the genetic divergence in 30 sorghum genotypes for 14 characters to determine genetic diversity using D² analysis and principal component analysis, D² values ranged between D² = 80.0061 and D² = 3471544.8770 showing high genetic divergence between the genotypes, on the basis of the D² values 30 genotypes were grouped into 7 Clusters, Cluster-I with highest 14 genotypes and Cluster-VII with least 1 genotype, inter-Cluster values ranged between D² = 3171872.80 to D2 = 80396.26, while the intra-Cluster values ranged between D² = 27422.98 to D² = 2032.887 genetic divergence was recorded maximum for transpiration rate (99.1%) on the other hand principal component analysis showed Eigen values > 1 for first four principal components which altogether contributed to 77% of the total genetic divergence.
