Abstract

A study was carried out on the thirty genotypes of chickpea to study the nature and magnitude of genetic divergence using Mahalanobis's D2 Statistics. The data were recorded on eight important quantitative traits from the genotypes grown in Randomized Block Design having three replication. The thirty chickpea genotypes were grouped into six clusters. The cluster I shows largest cluster with eight genotypes. Highest inter cluster distance was observed between cluster IV and cluster V, followed by cluster V and VI. The cluster VI was identified for pods per plant and seed yield per plant. Whereas genotypes included in cluster II were of early maturity with early flowering habit and average plant height. Genotypes included in these two clusters can be utilized for future crop improvement programme.
