Research is needed to determine the extent to which plant parasitic nematodes are reducing cowpea production in West Africa, and the extent to which this problem can be solved by breeding nematoderesistant cowpea cultivars. This information will be
critical in guiding cowpea breeding for nematode resistance in different agro-ecological zones. In this project, the focus is on Senegal and Burkina Faso. Development of cultivars with nematode resistance is expected to contribute to increases and improved stability in cowpea yield.
1. Determine species composition and incidence of nematode parasites through standard survey procedures within each Host Country cowpea-growing region. 2. Determine the susceptibility or resistance of common Host Country cowpea genotypes and UC-R's advanced breeding lines to the most important nematode species on cowpeas.
