Identification of new sources of resistance to Striga gesnerioides in cowpea Vigna unguiculata accessions
The parasitic weed, Striga gesnerioides, is a major threat to cowpea productivity throughout the savannas of West and Central Africa. The
identification of sources of S. gesnerioides resistance and their incorporation in ...
Adoption and Ex-post Impacts of Improved Cowpea Varieties on Productivity and Net Returns in Nigeria
Cowpea covers the largest area of any grain legume in Africa and is especially important in West Africa where Nigeria and Niger alone account for over 75% of the total cowpea production in the world. Despite successes of ...
Screening wild vigna species and cowpea (Vigna unguiculata) landraces for sources of resistance to striga gesnerioides
This chapter presents the results of a study conducted on the experimental field of the International Institute of Tropical Agriculture (IITA) in Minjibir, Kano State, Nigeria, during the planting seasons of 2012 and 2013 ...
Selection from segregating population across major agroecologies
A wild cowpea relative TVnu 1158 was identified three years ago and crossed to two cultivated lines IT99K-573-1-1 and IT98K-556-6. A total of 244 F9 Recombinant Inbred lines (RILs) from TVnu 1158 x IT99K-573-1-1 were ...
Effect of phosphorus (P) application on nutrient uptake, biomass, pod and seed formation in cowpea (Vigna unguiculata (L.) Walp])
Phosphorous (P) deficiency is a serious problem which limits the
productivity of cowpea in sub-Saharan Africa.
• P deficiency affects negatively the formation of nodule (1, 2) and the
symbiotic fixation of N2 by limiting ...

Suzuki, K., Fatokun, C. & Boukar, O. (2016). Responses of cowpea genotypes to rock phosphate application. Poster. Pan African Grain Legumes and World Cowpea Conference: sustainable grain legume systems for food income and ...
Screening cowpea germplasm (cultivated and wild relatives) for aphid resistance
A total set of 376 entries including 374 mini-core accessions, 1 resistant check (TVu801) and 1 susceptible check (TVx 3236) were evaluated in screening cages at Kano and screen house at Cotonou for resistance to cowpea ...
