Walp.] is an important grain legume which is widely grown in Sub-Saharan Africa (SSA) for food and feed. Its grain contains high levels of protein, energy, micro- and macro-nutrients. In SSA cowpea productivity is considerably low due to a wide array of abiotic and biotic stresses, and socio-economic constraints. This review summarizes challenges and constraints to cowpea production, breeding methods and progress, genetic variation and analysis of cowpea. Therefore, this review could serve as baseline informationenBreedingGenetic variationMacro-nuetrientsCowpea productivityArticle
