An investigation was carried out among the twenty five genotypes of chickpea to study the nature
and magnitude of genetic divergence using Mahalanobis’s D2 Statistics. The data were recorded on ten
important quantitative traits from the genotypes raised in Randomized Block Design having three replication.
The twenty five chick pea genotypes were grouped into six clusters. The cluster I shows largest cluster w ith
eight genotypes. Highest inter cluster distance was observed between cluster III and cluster VI, followed by
cluster I and VI. Three characters viz. harvest Index, 100 seed weight and number of pods per plant contributed
maximum in manifestation of genetic diversity. Number of pods per plant had maximum Phenotypic and
Genotypic Coefficient of Variation (PCV and GCV), followed by Biological yield per plant and 100 Seed
weight. A moderate to high degree of Heritability and Genetic Advance was observed for number of Pods per
pant, Harvest index and Biological yield. The genotypes KPJ 59, PBJ 1 and Pusa 329 were identified as
genetically diverse parents, which can be utilized for future crop improvement programme
Key words: Chickpea, inter cluster distance and intra cluster distance, genetic variability, D2 statistics, , ,
