Inter-cluster distance

The present study was conducted to evaluate the genetic divergence among twenty five pigeonpea germplasm using Mahalonobis D2 statistics for seven different traits during kharif 2015. Analysis of variance depicted the significant differences among the traits which indicated the presence of variability in the germplasm. D2 clustering grouped the genotypes into ten clusters. Based on the intercluster distance (1844.86) cluster VIII and X were the most diversified clusters and genotypes from these clusters can be used in the hybridization programme for further improvement.

Fifty germplasm of bread wheat used to study the nature and magnitude of genetic divergence using Mahalanobis’s D2 statistics. The data for twelve important quantitative traits recorded from the genotypes raised in Randomized Block Design having three replications. The fifty genotypes were grouped into eight clusters. Cluster I was largest with fourteen genotypes followed by cluster IV with ten genotypes.

The nature and extent of genetic diversity were assessed among 57 pigeonpea accessions comprising release varieties, farmer varieties and reference varieties. All the accessions were grouped into eight different non-overlapping clusters. Among them cluster I, having 17 accessions, emerged with highest number of entries followed by cluster V with 9 accessions, cluster III with 7 accessions, cluster IV with 6 accessions, cluster VI, VII and VIII constituted by 5 accessions each while cluster II, comprised 3 accessions, had least number of entries.
