Abstract

Present investigation comprised of 38 pigeonpea genotypes was conducted during kharif, 2022-23 crop season to estimate the genetic parameters, character association between yield and its component traits. High estimates of PCV and GCV were recorded for the characters like primary branches per plant, seed yield per plant, pods per plant, secondary branches per plant, plant height and 100-seed weight. High estimates of heritability associated with high genetic advance were obtained for the traits days to 50% flowering, plant height, pods per plant, pod length, seeds per pod, 100 seed weight and seed yield per plant representing that the heritability for these traits is most likely due to the additive gene effects. The trait number of pods per plant not only exhibited high positive direct effect but also positively and significantly correlated with seed yield per plant indicating that this component trait is governed by additive gene action and direct selection for this trait may cause desirable improvement in seed yield per plant.

Conclusion

On the basis of present findings, it can be concluded that the trait like pods per plant not only exhibited high estimates of heritability and genetic advance as percent mean, but it also contributed maximum towards the dependent variable seed yield per plant besides showing high positive correlation with seed yield per plant. This indicated that this component trait is governed by additive gene action and direct selection for this component trait may results in desirable improvement in seed yield per plant.
