Genetic divergence analysis of yield and its contributing traits in tall field Pea (Pisum sativum L.)

Abstract

The experimental material consisting of forty advance genotypes including two checks (Rachna and Shikha) was evaluated in Randomized Block Design with three replications for eleven characters by using Mahalanobis’s D2 statistic. The clustering pattern of 
genotypes showed no definite relationship between genetic divergence and geographical distribution of genotypes. The genotypes were grouped into seven clusters. The maximum ten lines were put cluster IV, it had maximum intra-cluster distance while inter-cluster distance was highest between I and II. Cluster means indicated that none of the clusters was superior for all the characters studies; however hybridization between genotypes belonging to different cluster (viz. Ist and IInd) is suggested for development of superior genotypes in field pea.
