Genetic diversity among 495 accessions of chickpea collected from different agro-ecological zones of India was assessed for several qualitative and quantitative traits. These accessions were grown in the augmented design with 3 intermittent checks ‘BG 256’, ‘K 850’ and ‘L 550’ after every fifteenth row. Wide range of variabi lity was obse rved for both qual itative and quantitative traits. The number of primary branches, 100 seed wei ght (g) and days to maturity showed moderate to high he ri tabili ty and geneti c advance. This sugge sts that the selection based on these traits would be useful in improving the grain yield. The diversity index indicated ample genetic variation for seed yield per plant in the present set of materials. Therefore, a direct selection based on seed yield and component traits may be practiced to select better genotypes, which could be utilized for development of superior high yielding varieties.
