Correlation and path analysis was carried out using 12 cross combinations of cowpea in F, and F, generations for nine component characters including seed yield. Number of branches per plant. number of pods per plant and plant height had positive correlation with seed yield both at genotypic and phenotypic levels in F, and F, generations. Path analysis showed positive direct effects of number of branches per plant. plant height, pod length. hundred seed weight on seed yield in F, generation while the traits hundred seed weight and seeds per pods had positive direct effect on seed yield in F, generations. These traits should be given more emphasis while selecting for improvement in seed yield per plant.
