Genetic studies of dual-purpose traits in cowpea was carried out at Teaching and Research Farm of Joseph Sarwuan Tarka University, Makurdi, Nigeria. The objective of the study was to understand the gene action controlling harvest and leaf-yield indices in cowpea and to identify the most appropriate breeding strategies for improving these traits. Six generations viz: P1, P2, F1, F2, BC1 and BC2 constituted the experimental material. They were grown in a Randomized Complete Block Design with three replications. Data were obtained on Seed yield, dry leaf weight at maturity, total biomass, biological yield, leaf-yield index, harvest index. Statistical analyses conducted included analysis of variance, scaling tests and gene effects, heritability and genetic advance under selection. Significant variation existed among the generations in the two crosses for all the traits indicating sufficient diversity for those traits. Non-allelic interactions along with additive and dominant components played pertinent role in the determination of various characters in cowpea. Inheritance of all traits studied in both crosses were governed by duplicate gene action except for biological yield in Cross II where it was governed by complementary gene action. Selection in later generation for duplicate gene action is recommended. Moderate to high heritability and genetic advance exhibited by most of the traits indicated that heritability was due to additive gene effect. The presence of both additive and non-additive gene effects, moderate to high heritability coupled with moderate/high expected genetic advance in inheritance of most of the traits, suggest that pureline method of breeding could be employed. Breeding methods involving crossing like biparental, pureline breeding, mass selection, that take care of both additive and non-additive gene action should be adopted for improvement of various characters studied.
