Cowpea is an important food crop in the dry savannas of West and Central Africa because of its high protein content. Yields are, however, considerably reduced by the parasitic angiosperm Striga gesnerioides. Field trials over 2 years in two localities in northeast Nigeria evaluated the performanc...

Cowpea is an important food legume and versatile crop in the savannas of northeast Nigeria. Despite the high potential for production in this region, insect pests are a major constraint. A study was conducted to evaluate the response of diverse cowpea genotypes to different schedules of spraying ...

The experiment was conducted to test the in vitro regeneration efficiency of cowpea shoots via embryonic axes explants and the effect of benzyl amino purine (BAP) concentration on shoot formation. A total of 600 explants (embryonic axes) were plated from which 237 shoots were regenerated. The ave...

Parasitism of crop plants by Striga species is a major constraint in the savanna zones of West Africa. Farmers ranked Striga as a leading constraint during a livelihood analysis of 30 communities in northeast Nigeria. A field survey was conducted to ascertain the extent of infestation by Striga s...

Cowpea Vigna unguiculata (L.) Walp. is an important component in mixed cropping systems that are appropriate to the agro-ecological characteristics of the West African savannah. However, the contribution of cowpea to overall productivity of the systems is reduced by a number of insect pest specie...

A rapid and reproducible in vitro plant regeneration procedure was developed for embryonic axis explants of cowpea [Vigna unguiculata (L.) Walp]. Moderate levels of 6-benzylaminopurine (0.5-2 mg l-1) were effective in inducing multiple shoots on decapitated embryonic axes on a Murashige and Skoog...

The larval parasitoid guild of the cowpea pod borer Maruca vitrata was studied on wild and cultivated host plants in Southern and Central Benin, West Africa. A total of eight parasitoids, seven of which belonging to the Hymenoptera: Braconidae, and one to the Diptera: Tachinidae, were observed ex...

The success of most crop improvement programs largely depends upon the genetic variability and the heritability of desirable traits. The magnitude and type of genetic variability help the breeder to determine the selection criteria and breeding schemes to be used for improvement purposes. A scree...

Cowpeas suffer major yield losses due to insect pests, so insect resistant cowpea varieties are being developed to minimize insecticide use in integrated pest management. Experiments during the cropping seasons of 2002–2004 at Kano, Nigeria, evaluated four cowpea varieties and five combinations o...

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...
