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 ...
Flower bud thrips, Megalurothrips sjostedti is the most severe field pest of cowpea that causes massive flower abortion which eventually results to substantial yield reduction in Africa. There is paucity of information on the mode of gene actions controlling inheritance of resistance to flower bu...
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...

Evaluation of cowpea germplasm lines for protein and mineral concentrations in grains
Cowpea (Vigna unguiculata spp unguiculata) is adapted to the drier agro-ecological zones of West Africa where it is a major source of dietary protein and widely used as a fodder crop. Improving the productivity of cowpea can enhance food availability and security in West Africa. Insect predation ...

Regulatory considerations surrounding the deployment of Btexpressing cowpea in Africa: report of the deliberations of an expert panel
The genetic diversity in wild cowpea was assessed using cowpea derived simple sequence repeat (SSR) markers. A total of forty eight wild cowpea
lines collected from diverse geographical locations in Africa were used for the study. Twelve SSR markers were selected for amplification of DNA
of the t...
The first major insect pest of cowpea at reproductive stage is the flower bud thrips (FTh), which, if not
controlled, is capable of causing significant grain yield reduction. Breeding for resistance to FTh in
cowpea has been hindered by the quantitative nature of the resistance, and the breakdown...

Genetic mapping of quantitative trait loci (QTLs) with effects on resistance to flower bud thrips (megalurothrips sjostedti) identified in recombinant inbred lines of cowpea (Vigna unguiculata (L.) Walp)
Cowpea is an important legume in sub-Saharan Africa where its protein rich grains are consumed. Insect pests constitute a major constraint to cowpea production. Flower bud thrips (FTh) is thefirst major pest of cowpea at the reproductive stage and if not controlled with insecticides is capable of...
Multi‐parent advanced generation inter‐cross (MAGIC) populations are an emerging type of resource for dissecting the genetic structure of traits and improving breeding populations. We developed a MAGIC population for cowpea (Vigna unguiculata L. Walp.) from eight founder parents. These founders w...

A multi-parent advanced generation inter-cross (MAGIC) population for genetic analysis and improvement of cowpea (Vigna unguiculata L. Walp.)
Cowpea is a self-pollinated crop and this is encouraged by the arrangement of floral parts. However, outcrossing has been reported and frequency of occurrence could vary depending on the genotypes involved and the environment where grown. Insects have been implicated in the movement of pollen in ...
Factors responsible for successful rescue of immature embryos of cowpea [Vigna unguiculata (L.) Walp.] and V. vexillata (L.) and for in vitro embryo development were studied. A new basal medium for embryo development in vitro was formulated on the basis of the mineral composition of embryos. Sucr...
