 ABSTRACT

The present investigation entitled was carried out at experimental farm of Department of Horticulture, AKS University, Satna (M.P.) during Kharif season of year 2019-20. The experiment was conducted in Randomized Block Design having 12 treatments i.e. 12 genotypes of Cowpea in three replications. Twelve diverse varieties of Cowpea collected from different sources and all the genotypes are grown with three replications in 2.4 m2 plot and the plant keeping 60 x 25 cm maintained between Row and Plant distance. They were evaluated for growth yield and quality attribute for all the traits. High heritability (77.44%) coupled with high genetic advance (52.08) observed for green pod yield per plant, very high heritability (94.47%) for plant height at final harvest indicated that phenotypic selection would be effective for genetic improvement in these traits. High magnitude of phenotypic GCV and PCV (i. e. >20 per cent) were observed for Economic yield (kg/plot) (71.97 per cent and 81.76 per cent, respectively), followed by Biological yield (kg/plot) (61.59 and 79.96 per cent, respectively. whereas, the moderate magnitude of GCV and PCV (10-20 per cent) were observed for Harvest index (19.78 and 35.53 per cent), respectively) and Plant height (19.52 and 25.86 per cent), respectively. The low magnitude GCV (<10 per cent) was also observed for the character Number of primary branches/plant (8.60 and 14.49 per cent, respectively) Days to 50% flowering (5.10 and 6.88 per cent, respectively), Days to 1st flowering (1.22 and 2.10 per cent, respectively.

Keywords: Cowpea, Heritability, Genetic Variability, Genetic Advance.
