An experiment was conducted during Rabi, 2020-21 at Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (Allahabad) consisting of 32 chickpea genotypes obtained from ICAR-Indian Institute of Pulses Research, Kanpur, U.P in RBD with three replications. The data was recorded on 13 characters. Heritability estimates along with genetic advance as percent of mean was high for No. of pods per plant, No. of seeds per plant,100-seed weight and Grain yield per plant. Seed yield per plant exhibited positive and highly significant correlation at both the levels with Number of secondary branches per plant, Number of pods per plant, Number of seeds per plant and biological yield per plant (g). The significant correlation with days to 50 % flowering suggests its use in breeding programme for earliness. The characters viz., Harvest index (%), Biological yield per plant (g), Number of pods per plant, Number of primary branches per plant, and Days to 50% flowering had the highest direct positive effect on seed yield per plant
