Abstract: An investigation was carried out using 60 genotypes of vegetable cowpea to find out the correlation coefficients and path coefficients. The material was evaluated in a randomized block design with three replications at the Vegetable Research Station, J. A. U., Junagadh during summer 2018. The observations were recorded on 12 characters viz., days to 50% flowering, days to first green pod picking, number of primary branches per plant, plant height (cm), pod length (cm), pod width (cm), number of pods per plant, number of pods per cluster, ten pod weight (g), number of pods per plant, plant spread (cm) and green pod yield per plant (g). The values of genotypic correlations were higher than their corresponding phenotypic correlations. The pod yield per plant exhibited significant and positive correlations with number of primary branches per plant, plant height, pod length, number of pods per plant and number of seeds per pod at both genotypic and phenotypic levels. The path coefficient analysis showed the high positive direct influences on pod yield per plant through number of primary branches per plant and pod length and hence, due emphasis should be placed on these characters while selecting for high yielding types in vegetable cowpea.
