Abstract: Study on few chickpea genotypes for genetic divergence was carried out with respect traits related to seedling growth in the laboratory of the department of Genetic and Plant Breeding, BCKV, Mohanpur, Nadia, West Bengal. Out of characters under study, the highest contributor towards total divergence was shoot length (26.821%). The genotypes could be grouped into 8 clusters based on the relative magnitude of D² values. Cluster I had the highest number of genotypes i.e. 56. The values of intracluster distances varied from 12.425 (cluster I) to 99.684 (cluster VII). The highest intra-cluster distance was observed for cluster VI (99.684). Dendrogram was drawn by taking Euclidean distance as a measure of genetic distance following ‘Unweight Pair Group Method using Arithmetic Averages’ (UPGMA). The genotypes IPC 2010-37, AGBL 122 and 24017-1-1 hold a greater distance and are were widely apart from ICCV 13305, ICCV 13306 and AGBL 134. Therefore hybridization may yield greater heterosis.
