The present experiment was carried out at field experimentation centre site of the Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad to study about genetic variability, correlation and path analysis in fifty chickpea germplasm during Rabi, 2017-18. The analysis of variance revealed significant differences among the genotypes for all the characters under the study, indicating a high degree of variability present in the material. The values of PCV were found greater than GCV for all the traits studied indicating environmental factors influencing the characters. High PCV and GCV were observed for effective pods per plant (36.41% and 34.38%) followed by total number of pods per plant (34.85% and 32.70%) and seed index (29.98% and 29.78%) indicated large extent of genetic variability for these traits in the material. High heritability were recorded by seed index (98.61%) followed by harvest index (90.81%), effective pods per plant (89.14%), total number of pods per plant (88.01%), secondary branches per plant (84.42%), primary branches per plant (84.31%) and plant height (81.03%).High heritability along with high genetic advance was observed for the traits, viz., effective pods per plant, total number of pods per plant, seed index, primary branches per plant and secondary branches per plant indicated that the characters were mostly governed by additive gene effects. So direct selection of these characters based on phenotypic expression by simple selection method would be effective due to accumulation of more additive genes leading to further improvement. Grain yield per plant showed positive significant genotypic and phenotypic correlations with biological yield/plant, seed index, harvest index, effective pod/plant, total number of pods/plant and secondary branches per plant whereas significant negative correlations with days to 50% flowering respectively. At the both phenotypic and genotypic levels, biological yield per plant, harvest index, days to maturity, chlorophyll index and plant height had direct positive effect on grain yield per plant had given the highest contribution on yield per plant. So the utmost importance should be given to these characters during the selection for yield improvement in chickpea.
