Abstract:

In the present investigation, 21 F1s were generated by crossing seven lines and three testers following Line x Tester mating design. Nine yield traits of barley were studied on 21 crosses to estimate heritability in narrow sense, genetic advance in per cent of mean, phenotypic and genotypic coefficient of variation. The estimates of heritability in narrow sense were observed to be high for only two traits viz., days to maturity (57.83%) and ear length (31.54%); while some traits showed moderate heritability viz., harvest index (22.80%) and grains/spike (19.49). High heritability in narrow sense (h2n) coupled with high genetic advance in per cent of mean were recorded only for ear length while the remaining traits showed low genetic advance indicating non-additive gene action. The moderate estimates of phenotypic coefficient of variability were found in grain yield/plant, productive tillers/plant. Estimated of GCV were lower than PVC for all traits.
