Seed yield is the primary trait of interest, however, several secondary traits contributes in final yields. Contribution of various traits varies significantly, and therefore, identification of traits with their level of contribution into seed yield might help breeders in selection of high yielding cowpea varieties with simultaneous selection for seed along with trait(s) with higher contribution in final yields. We studied range of key secondary traits along with seed yield in cowpea genotypes to understand the hierarchy of contribution of various traits in seed yield. Analysis of variance revealed presence of significant variation among the genotypes for all the characters studied. Genetic coefficient of variation, heritability and genetic advance was high for seed yield. Path coefficient analysis clearly revealed that clusters of pod per plant exhibited maximum direct positive effect on seed yield per plant both at phenotypic and genotypic levels. However, pod length followed by plant height, test weight and pods per cluster exhibited negative direct effect phenotypically. We conclude that among various traits the clusters of pod per plant might be considered as a potential character contributing towards increasing seed yield which could be used as selection criteria along with seed yield for genetic improvement of cowpea genotypes.
