<p><b>Abstract:</b> <span style="font-family:"Times New Roman",serif;color:black">
Cowpea is a hardy, nutritious warm-season legume crop that is vitally important for food security in Africa, where it provides a primary source of protein that complements cereals in the diets. However, in the Sudano-Sahel region of West Africa typical cowpea
grain yields of smallholder farmers are far below known yield potential due to biotic and abiotic stresses. Many of these problems also affect cowpea production in the USA. In the Central Valley of California, the blackeye-type cowpea is grown as grain and/or
cover crops in cropping systems to disrupt pests and fix nitrogen for the soil. Root-knot nematodes (RKN), aphid, lygus, and Fusarium wilt diseases are prevalent in this region, causing significant reductions in yield and seed quality of standard cultivars;
RKN and aphids also affect the vegetable-type cowpea (Asian long bean) grown on diversified farms by disadvantaged Hmong farmers. The California Dry Bean Board, CDFA-USDA and USAID support our program to develop improved resistant varieties for sustainable
agriculture in West Africa and the USA. This effort is enabled by the rich collection of resources developed over years of collaborative research at UC Riverside. They include RKN biotype collections, field- and lab-based resistance bioassays, genetic markers
and germplasm collections of host crop genetic diversity. Quantitative trait loci (QTL) with major effects on resistance to RKN, aphid and other stresses have been identified. Favorable QTL haplotypes from African cowpea germplasm are stacked into new generations
using bi-parental and multi-parental marker-assisted breeding strategies. New improved varieties have been developed and released in West Africa and the USA, along with outreach activities to enable adoption. QTL near-isogenic lines also enable map-based cloning
and functional analysis of candidate genes underlying RKN resistance. Future research using cowpea to further advances in nematode resistance and genetic improvement of cowpea and other crops will be discussed.</span><o:p></o:p></p>
