| dc.description.abstract | The investigation on genetic studies of germplasm in chickpea (Cicer arietinum L.) was conducted on 54 genotypes of chickpea to know the variability, interrelationship among yield and its components, their direct and indirect effects on seed yield and genetic divergence among various genotypes of chickpea. 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 100 seed weight and number of pods per plant, while their estimates were lowest for number of seeds per pod. Heritability in broad sense was highest for 100 seed weight. High heritability ----------associated with high genetic advance as percent of mean observed for number of primary branches per plant, number of pods per plant, 100 seed weight and seed yield per plant suggesting non additive genetic control in their inheritance and scope for improving these characters through selection. Genotypic correlation coefficients were found to be of higher magnitude than the corresponding phenotypic ones. The characters, plant height, number of secondary branches per plant, number of pods per plant, number of seeds per pod were positively associated with seed yield per plant while number of secondary branches per plant, days to 50% flowering, days to maturity were negatively significant associated with seed yield per plant. Number of pods per plant, plant height, showed positive direct effects on seed yield while days to maturity, number of secondary branches per plant and other characters showed negative direct effects. The D2 statistics showed that there was adequate diversity among the genotypes with D2 values ranging from 14.44 to 216.67. On the basis of D2 values, fifty four genotypes studied were grouped into 8 clusters. On the basis of intercluster distance, cluster means per se performance, the genotypes viz., RCLG-79, RCLG-100, RCLG-8, RCLG52, RCLG-9, RCLG-469, RCLG-94, RCLG-10 were identified for their use in hybridization programme. | en_US |
