Abstract

Two F2:3 populations of cowpea were evaluated for 10 different quantitative traits during summer 2021 to study genetic variability parameters. Analysis of variance revealed significant differences among all the segregants of the population for most of the traits studied. High phenotypic coefficient of variance and genetic coefficient of variance were recorded for plant height, number of primary branches/plant, dry matter/plant and seed yield/plant in F2:3 population of VBN-1 × RC-19; number of primary branches/plant, number of pods/plant, dry matter/plant and seed yield/plant in F2:3 population of KBC-9 × PGCP-6. High heritability and GAM were recorded for plant height, number of primary branches/plant, number of pods/plant, pod length, number of seeds/pod, dry matter/plant and seed yield/plant in the F2:3 population of VBN-1 × RC-19; plant height, number of primary branches/plant, number of pods/plant, number of seeds/pod, dry matter/plant and seed yield/plant. This indicates the scope for improvement of these characters through selection.

Conclusion

High phenotypic coefficient of variance and genetic coefficient of variance were recorded for plant height, number of primary branches/plant, dry matter/plant and seed yield/plant in F2:3 population of VBN-1 × RC-19. High heritability coupled with medium genetic advance as per cent of mean indicated the presence of both additive and non-additive gene actions for the inheritance of these characters and high genotype × environment interaction.
