This review presents an overview of accomplishments on different aspects of cowpea breeding for drought tolerance. Furthermore it provides options to enhance the genetic potential of the crop by minimizing yield loss due to drought stress. Recent efforts have focused on the genetic dissection of ...
Cowpea, an indigenous crop to sub-Saharan Africa, is found mainly in the dry savanna regions along with cereals such as millets and sorghum. Cowpea is grown primarily for human consumption of the grains, which are rich in protein, carbohydrates and contain some minerals. The development and deplo...

omparative analysis of preferences and key criteria for selecting cowpea (Vigna unguiculata L. Walp.) varieties was conducted using the data collected from farmers’ participatory varietal selection (FPVS) activities conducted over 3 years with a total of 2401 farmers (1230 male and 1171 female) i...

Cowpea is an important crop for food security, as it is a primary source of protein and cash income for farmers in the dry
savanna areas of Sub-Saharan Africa. Improved varieties should contain reasonable amounts of protein in the grains, and to
ensure this, timely and cost-effective analytical m...

Cowpea is traditionally important as an affordable source of protein and minerals and of cash income in sub-Saharan Africa, especially for small-scale farmers who have limited options for food and cash crops. The development and deployment of cowpea varieties with improved nutrition and quality t...

Genetic diversity of physical, nutritional and functional properties of cowpea grain and relationships among the traits
The stay-green phenomenon is a key plant trait with wide usage in managing crop production under limited water conditions. This trait enhances delayed senescence, biomass, and grain yield under drought stress. In this study we sought to identify QTLs in cowpea (Vigna unguiculata) consistent acros...

A comparative analysis of farmers’ preferences on improved cowpea varieties was carried out based on the data obtained from farmers’ participatory varietal selection and questionnaire survey undertaken in south-eastern Niger and north-central Burkina Faso. The grain yield was consistently the mos...
