Observations were recorded for days to 50% flowering, days to maturity, plant height, number of primary branches per plant, number of secondary branches per plant, number of pods per plant, number of seed per pod, 100 seed weight, seed yield per plant. A wide range of variation was observed for the characters days to 50% flowering, days to maturity, plant height, number of secondary branches per plant, number of pods per plant, 100 seed weight and seed yield per plant however, narrow range of variability was observed for number of primary branches per plant, number of seeds per pod. Genotypic and phenotypic coefficient of variation were higher for seed yield per plant followed by plant height, number of pods per plant and number of secondary branches, while their estimates were lowest for number of seeds per pod, days to maturity. Heritability in broad sense was highest for seed yield per plant. High heritability associated with high genetic advance as percent of mean observed for number of primary, secondary branches per plant, number of pods per plant, 100 seed weight and seed yield per plant suggesting that selection of these traits would be effective for the desired improvement in chickpea. Genotypic correlation coefficients were found to be of higher magnitude than the corresponding phenotypic ones. The characters, plant height, number of primary branches per plant, number of secondary branches per plant, number of pods per plant, number of seeds per pod were significantly and positively associated with seed yield per plant. Number of seeds per pod, number of pods per plant, number of secondary branches per plant showed positive direct effects on seed yield while number of primary branches per plant showed negative direct effects. The D2 statistics showed that there was adequate diversity among the genotypes with D2 values ranging from 20.52 to 985.96. On the basis of D2 values, fifty two genotypes studied were grouped into six (6) clusters. On the basis of inter and intra cluster distance, cluster means per se performance, the genotypes viz., IC-275426, IC-275427, IC-275445, IC-327024, IC-327031, IC- IC-327056, IC-327029, IC327035 and IC-275429 were identified for their use in hybridization programme.ennullThesis
