Abstract:
The current study, entitled "Genetic Analysis in Cowpea (Vigna unguiculata L. Walp.)," was carried out at the AICRP on vegetable crops, Horticultural Research cum Instructional Farm, Department of Vegetable Sciences, Indira Gandhi Krishi Vishwavidyalaya, Raipur (21.23760 N. 81.70550E) during 2019-20. The trial used a randomized block design (RBD) with 27 treatment combinations and three replications, with genotypes assigned at random in each replication. The results showed that among the twenty-seven genotypes examined, Kesli 4 (79.78* kg), Nandghat 2 (79.77* kg), and Kesli 7 (79.44* kg) had the highest green pod production. The genotypes Bardwar 4 (56.96 kg), B. Bazar (57.94 kg), and Bhakhara had the least yield (57.38 kg). Based on the mean performance of cowpea genotypes, the genotypes Kesli 4, Nandghat 2, and Kesli 7 were deemed the most promising in terms of green pod production per hectare. The PCV was slightly greater than GCV, illustrating the role of environment in the manifestation of numerous traits under investigation. High magnitude of GCV were observed for the characters viz., days to germination (30.34), number of flower cluster per plant (27) and number of primary branches (23.35). High magnitude of PCV were observed for the characters viz., days to germination (33.10), number of flower cluster per plant (33.42), number of primary branches (29.82), number of secondary branches (21.32) and pod length (21.70). High estimate of heritability was recorded for fruiting duration (95.72%), days to first flowering (95.08), days to first fruiting (94.28%), days to 50% flowering (93.89%), days to final picking (90.24%), days to germination (84.04%) and 10 pod weight (74.69%). Path analysis revealed a positive direct correlation with days to germination, plant height, number of primary branches, number of secondary branches, days to first flowering, days to 50% flowering, days to first fruiting, fruiting duration, days to final picking, number of flower clusters per plant, number of pods per cluster, pod length (cm), 10 pod weight, percentage of pod setting per cluster in the present study. The aforementioned characteristics had a great influence on yield and can be considered for future hybridization techniques.
