For a mixture of reasons certain tropical crops which are important as primary or secondary food staples are relatively underresearched. The modem tools of molecular and cellular biotechnology offer the opportunity not only to make substantial gains in our knowledge of these crops, but also to ov...
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...
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 ...
Genetic diversity was investigated among fifty accessions of yard-long-bean (Vigna unguiculatasubspecies unguiculatacultivar group sesquipedalis) using simple sequence repeat (SSR) markers. Sixteen SSR primers were used to amplify DNA of the 50 accessions. A total of 63 polymorphic bands were det...
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...
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...
