GENETIC DIVERGENCE ANALYSIS FOR YIELD AND QUALITY TRAITS IN PIGEONPEA [Cajanus cajan L.]
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 52
Abstract
Genetic divergence among 38 genotypes of pigeon pea belonging to different eco geographical regions was studied by using Mahalanobis D2 statistics. They were grouped into 7 clusters and clustering pattern of genotypes and genetic diversity was independent of their pedigree. Hence, selection of parents for hybridization should be more based on genetic diversity rather than geographic diversity. Among the seven clusters, cluster IV having two genotypes [SKNP 0505 and Manak] registered maximum mean values for seed yield per plant, number of pods per plant, total protein content, total phenol content and methionine content. These two genotypes were thus found having genetic make-up for high productivity with desirable biochemical quality. Similarly, the cultivar GT 101 was found better for seed yield per plant, pods per plant and tannin content. The cultivar Manak, UPAS 120 and Vipula were found best source of genes for phenol content to be exploited through hybridization programme.
