Abstract:
The current experiment entitled, "Genetic Variability, Heritability, Correlation Studies and Path Coefficient in Cowpea [Vigna unguiculata (L.) Walp..]”, was conducted for experimentation focus at field of Department of Horticulture, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, during Kharif season 2020-2021. The experiment was carried out with 36 genotypes secured from SHUATS, Prayagraj in Randomized Block Design (RBD) with three replications. The moderate magnitude of genotypic coefficient of variance GCV was recorded for TSS (⁰Brix), pod yield (q/ha), pod yield plot-1 (kg), pod yield (gm) plant-1, number of seeds plant-1 and number of pods plant-1. The most elevated magnitude of the phenotypic coefficient of variance PCV was recorded for TSS (⁰Brix). Genotypic correlation coefficient analysis revealed that pod yield (t/ha) showed a positive significant association with plant height (cm) (0.301**) at genotypic level, number of pods per plant (0.743** & 0.578**), number of seeds per plant (0.558** & 0.474**), pod weight (g) (0.718** & 0.519**), pod yield per plant (0.932** & 0.846**), pod yield per plot (0.914** & 0.850**) and TSS (⁰Brix) in Pod (0.234* & 0.194*) at both genotypic and phenotypic level. The most elevated direct beneficial outcome on Pod yield (q/ha) was displayed by plant height (cm) (0.0277) at genotypic level, days to first picking (0.0292 & 0.0482), number of pods per plant (0.0417 & 0.0748), no. of nodes per plant (0.0022 & 0.0382), length of the pods (cm) (0.0313 & 0.0058), number of seed per plant (0.144 & 0.0374), 100 seed weight (gm) (0.0302 & 0.0579), pod weight (gm) (0.1699 &0.1312), pod yield per plant (gm) (0.3952 &0.3452) and pod yield per plot (kg) (0.4029 &0.3844) at both genotypic and phenotypic and number of branches per plant (0.0563), number of seeds per plant (0.0705) and TSS (⁰Brix) (0.0065).
