Abstract:

The study was undertaken on the 30cowpea genotypes along with one check (Pant lobia-5) to study the genetic variability, correlation and path analysis at Field Experimentation Centre, Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences(SHUATS), Prayagraj during Kharif 2016 in Randomized Block Design with three replications. Analysis of variance showed highly significant differences among (29+1check) cowpea genotypes for 13 yield contributing characters studied. Maximum genotypic and phenotypic variance was recorded for plant height, days to maturity, pods per plant and biological yield. Maximum GCV and PCV were recorded for pods per plant, primary branches per plant and pod length. High heritability coupled with high genetic advance as percent of mean was recorded for pods per plant, primary branches per plant and plant height. The genotypic and phenotypic correlation coefficients were computed among 13 characters’ days to 50% flowering, days to 50% pod setting, pods per plant, 100 seed weight, harvest index and biological yield showed highly significant positive association with seed yield at both phenotypic and genotypic levels. While plant height is significant negative correlation with the seed yield at both phenotypic and genotypic levels. Path values revealed that days to 50% flowering, pods per plant, clusters per pod, harvest index, biological yield showing direct positive effect on seed yield at both phenotypic and genotypic levels. Primary branches per plant showed direct and negative effect on seed yield at both phenotypic and genotypic levels. Pod length,100 seed weight, showed direct and positive effect on seed yield at genotypic level. Days to 50% maturity, days to 50% pod setting, plant height, seeds per pod showed direct positive effect on seed yield at phenotypic level.
