Estimates of inter-generation parameters indicated that the heritability values calculated from the regression of F4 lines using conventional and standard unit procedures were significant in PS (HY) and PS (EF) in all the four crosses for seed yield per plant. The expected selection differential was higher than observed values in case of PS (EF) in all the four crosses, while it was lower in case of PS (HY) in all the four crosses of chickpea studied. The predicted genetic gain was lower than the realized gain in both the selection methods in all the four crosses except PS (EF) in cross 1. The highest estimate of realized heritability was observed in PS (HY) in cross 4, which was followed by PS (EF) in cross 4 and PS (HY) in cross 3. The PS (HY) in cross 1 and cross 2; and PS (EF) in cross 2 and cross 3 showed moderate estimate of realized heritability. Significant phenotypic correlation coefficients between F2 and F3 lines were obtained for seed yield per plant and number of pods per plant in PS (HY) procedures of all the four crosses except for number pods per plant in cross 4; in PS (EF) procedures of all the four crosses except for cross 2 and number of pods per plant in cross 3.
