D2 analysis and principal component analysis to assess genetic divergence in Sorghum bicolor (L.) moench for yield and its related attributes


Gyan Pratap Singh Bhadouriya and Narendra Singh Bhadouriya

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.
