Abstract

The present experiment was carried out during February to May, 2021 in Research Field, Department of Horticulture, SHUATS, Prayagraj, Uttar Pradesh. To study the genetic divergence studies in cowpea [Vigna unguiculata (L.) Walp.]. The experiment was conducted in Randomized Block Design (RBD), consisting of thirty three genotypes, replicated thrice. The result from the present investigation revealed that genotype IC 201098 (9871.32 kg/h) and genotype IC 202743 (9837.61 kg/h) are desirable with maximum pod yield respectively. The analysis of variance indicated highly significant differences among genotypes for almost all the characters. Heritability was recorded for all characters which were highly heritable except plant height at maturity (88.97 cm) and TSS (°Brix) 92.68, in which heritability was recorded moderate. PCV is higher than GCV for all characters except number of seeds per plant (31.10) which was recorded same. Higher magnitude of GCV and PCV was recorded for number of seed

Conclusion

The results from the present investigation revealed that maximum pod yield was recorded in IC 201098. Number of seeds per plant and plant height at maturity was recorded high estimates of GCV and PCV. Plant height at flowering (cm), Plant height at maturity (cm), Number of nodes on main stem, Days to 50% flowering, days to 50% maturity, no. of pods per peduncle, no. of pods per plant, no. of seeds per plant, TSS (°Brix) & Protein (%) shows significant positive correlation with pod yield at phenotypic and genotypic level. At genotypic and phenotypic level, plant height at flowering (cm), Days to first pod formation, Days to 50% flowering, Pod length (cm) & TSS (0Brix) had direct positive effect on Pod yield per plant.
