Character association and path co-efficient analysis were carried out using 25 genotypes of cowpea for 10 yield attributing traits. Character association analysis revealed that the characters number of pods plant-1, number of clusters plant-1, number of branches plant-1, 100 seed weight, days to 50 per cent flowering and days to maturity exhibited significant and positive association with seed yield plant-1 indicating that selection based on these characters would bring about simultaneous improvement of the yield. Path co-efficient analysis revealed that number of pods plant-1 exhibited the highest positive direct effect on seed yield plant-1 followed by100 seed weight, number of clusters plant-1, days to maturity, plant height, pod length, number of seeds pod-1 and number of branches plant-1indicating that direct selection of these characters would be rewarding for improvement of the yield.
