Abstract

Genetic variability was studied in BC2F4 backcross derived lines in chickpea during Rabi 2021-2022 under irrigated and non-irrigated environments. The study revealed highly significant differences for all the yield and its contributing traits, indicating the presence of high genetic variability. The phenotypic coefficient of variation was found high in drought stress trial for seed yield per plant and yield per plot. Biomass per plant, number of pods per plant and proline recorded moderate genotypic and phenotypic coefficients of variation under both stressed and non-stressed condition. This indicates substantial scope for improvement in these characters after hybridization and subsequent selection. High heritability coupled with high genetic advance was found for the traits viz., biomass per plant, number of pods per plant, seed yield per plant in both environments, and also for yield per plot and proline in drought stress trial indicating that the traits are governed by additive gene action and reliability of these characters for selection.

Keywords

Genetic variability, PCV, GCV, Heritability, Genetic advance.

Conclusion

Hence, from the present finding it is concluded that the advanced chickpea backcross derived BC2F4 lines used in the present study has plenty of variability for most of the traits and these traits should be taken into account while selecting superior plants for further improvement of yield and yield attributing traits in chickpea.
