“…Lopes, Gomes, and Filho () reported that the number of genes that control 100‐seed weight in cowpea is five and the high values for narrow sense heritability indicates that selection for seed size can be made in early generations. Pandey and Dhanasekar () reported the presence of connate foliaceous stipules of primary leaves and their inheritance in cowpea genotype EC394736. They found the rudimentary stipules (RS) to be dominant over foliaceous stipules (FS).…”

Cowpea, Vigna unguiculata (L.), is an important grain legume grown in the tropics where it constitutes a valuable source of protein in the diets of millions of people. Some abiotic and biotic stresses adversely affect its productivity. A review of the genetics, genomics and breeding of cowpea is presented in this article. Cowpea breeding programmes have studied intensively qualitative and quantitative genetics of the crop to better enhance its improvement. A number of initiatives including Tropical Legumes projects have contributed to the development of cowpea genomic resources. Recent progress in the development of consensus genetic map containing 37,372 SNPs mapped to 3,280 bins will strengthen cowpea trait discovery pipeline. Several informative markers associated with quantitative trait loci (QTL) related to desirable attributes of cowpea were generated. Cowpea genetic improvement activities aim at the development of drought tolerant, phosphorus use efficient, bacterial blight and virus resistant lines through exploiting available genetic resources as well as deployment of modern breeding tools that will enhance genetic gain when grown by sub-Saharan Africa farmers.

“…Changes of morphological, biochemical and physiological traits in response to drought stress for several V. unguiculata cultivars have been reported . The root system or rooting pattern are closely related to drought‐tolerance mechanisms in legume crops . To evaluate and screen cowpea drought‐tolerance, several parameters of the root system have been used, such as root length density, rooting depth and root dry matter .…”

Cowpea: a legume crop for a challenging environment

et al. 2017

Cowpea is a grain legume native from Africa and is a primary source of protein for millions of people in sub-Saharan Africa and other parts of the developing world. The main important characteristics of this crop include a good protein quality with a high nutritional value, its nitrogen-fixing ability, and an ability to be more drought- and heat-tolerant than most of its legume relatives. In a research perspective, studies of cowpea are relatively scarce, despite its relevance to agriculture in the developing world and its resilience to stress. The present review provides an overview of different aspects of cowpea, with a special emphasis on the molecular markers for assessing genetic diversity, as well as on biochemical and transcriptomic data with respect to evaluating cowpea drought stress tolerance. The integration of both datasets will be useful for the improvement of cowpea because research on drought stress tolerance is of major interest for this crop in a challenging environment. © 2017 Society of Chemical Industry.
