Abstract
The present investigation consists of 31 genotypes of Chickpea including one check, which were grown in the Field Experimentation Centre of the Department of Genetics and Plant breeding, SHUATS, Prayagraj during Rabi 2019-20 following RBD with three replications. The data were recorded on 13 characters to study the amount of genetic variability, heritability, association of yield contributing components with yield and direct and indirect effects of yield contributing component with yield and direct and indirect effects of yield contributing components in the chickpea genotypes. Based on the mean performance genotype Phule-4-5 followed NBEG-3, IPC-06-11, IPC-97-29 and CSJ-515 were identified as best genotypes for seed yield per plant. High significant variation was obtained for all characters studies. High heritability estimates were observed for No of seeds per plant followed by No of Pods per Plant, No of Secondary Branches, No of Primary Branches, Harvest Index, Seed Yield per plant, No of seeds per pod, Biological yield, Days to 50% Flowering, 100 Seed weight. Plant height, Days to Maturity and Days to 50% Pod setting. High values for heritability indicates that it may be due to higher contribution of genotypic components. High genetic advance as percent of mean was recorded high for No of seeds per plant, No of pods per plant while moderate genetic gain is observed for Biological yield, Seed yield per plant, Harvest Index, No of Primary branches, No of Secondary Branches, No of seeds per pod, 100 seed weight. Traits exhibiting high heritability coupled with genetic advance as percent of mean suggest that the traits are governed by additive gene action, equal Contribution of additive and non-additive gene action respectively. Genotypic and Phenotypic correlation coefficient analysis revealed that Seed yield per plant showed highly significant and positive association with Days to maturity (0.905**) and Number of pods per plant (0.554**). The Phenotypic path coefficient analysis results showed that positive and direct effect on Seed yield was exhibited by Days to maturity, No of Primary branches, No of secondary branches, No of pods per plant, 100 Seed weight, Biological yield, Harvest index. The Genotypic path coefficient analysis results showed that positive and direct effect on Seed yield was exhibited by Days to 50% Pod setting, Days to maturity, No of Primary branches, No of secondary branches, Biological yield, Harvest index.
