Abstract: A field experiment was conducted during kharif 2016 at Cotton Research Station, JAU, Junagadh (Gujarat). The experiment was laid out in Randomized Complete Block Design with three replications. The present investigation was carried out on 54 diverse genotypes of cowpea to study the correlations and path coefficient for different traits viz., Days to 50 per cent 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 cluster per plant, Number of seeds per pod, Number of pods per cluster, Leaf chlorophyll content, Ten pod weight (g),Hundred fresh seeds weight(g) and Green pod yield per plant(g). Association analysis between green pod yield per plant and other thirteen quantitative characters revealed that green pod yield per plant was highly significant and positively correlated with number of pods per plant (rg=0.6812, rp=0.6467) and ten pod weight (rg=0.2683, rp=0.2600) both at genotypic and phenotypic levels Path coefficient analysis indicate the highest positive direct effect on green pod yield per plant by number of pods per plant followed by number of clusters per plant and ten pod weights.
