Abstract

Two cross combinations of cowpea in F4 generation were studied for correlations among nine characters. Seed yield per plant showed strong positive association with hundred seed Weight, number of seeds per pod, plant height, crude protein content, number of pods per plant and number of branches per plant. Crude fibre content showed strong negative association with seed yield. Path analysis revealed that number of branches per plant had the highest positive direct effect on seed yield followed by number of pods per plant in both crosses. Crude protein content had highest direct effect on seed yield in one cross combination. Plant height and crude fibre content showed negative direct effect on seed yield. Number of pods per plant, number of branches perplant, number of seeds per pod and crude protein content can be used as reliable parameter for seed yield in cowpea.
