To estimate the genetic diversity among the 104 chickpea genotypes, an experiment was carried out based on Augmented Randomized Complete Block Design with eight blocks in two locations during rabi seasons of 2015-2016 and 2016-2017. All the 104 chickpea genotypes were classified into 5 clusters. The inter-cluster distances were more than intra-cluster distances this indicates that a sufficient amount of genetic variability was present in the study material. Inter cluster D2 values ranged from 62.50 to 87.52. Maximum inter cluster distance was between cluster III and IV (87.52) while minimum inter cluster distance (62.50) was observed between cluster I and II indicating presence of diversity in these clusters. The cluster II showed maximum intra cluster D2 value (59.10). Among all the characters, number of pods per plant contributed the maximum (29.69 %) to the diversity by taking first rank in 1468 times out of 4945 combinations. Cluster III which consists of 5 genotypes showed maximum mean value for number of pods per plant, shoot phosphorus concentration and seed yield per plant may be of importance for yield characters. Diverse clusters namely, III and V consists of diverse parents hold good promise for superior hybrids for desirable characters and thereby creating greater possibilities of obtaining phosphorus acquisition efficient with high yielders
