Abstract

Forty-nine kabuli chickpea genotypes were tested in 7 x 7 simple lattice designs at Jari in 2006/07. The objective of the study was to estimate genetic divergence among the forty nine Kabuli chickpea genotypes and clustering them into genetically divergent class. Cluster analysis revealed that the 49 kabuli chickpea genotypes were grouped into eight clusters. Distances between these clusters are significantly different for all the cluster combinations except between cluster I and IV. This indicates that there is an opportunity to bring about improvement through hybridization of genotypes from different clusters and subsequent selection from the segregating generations. Thus, crosses involving Cluster III with Cluster VII, and Cluster V with cluster VII are suggested to exhibit high heterosis and could result in segregants with higher seed yield. Principal component analysis indicated that four principal components explained about 79.92% of the total variation. Differentiation of the genotypes into different cluster was because of a cumulative effect of a number of characters, mainly phenological traits days to 50% flowering, days to maturity, number of primary branches plant-1 and number of seeds pod-1.
