1. Identify bean genotypes capable of yielding 20-30% more than traditional varieties in low P soils, and deploy this germplasm through been breeding programs in Central America (primary focus) and Eastern Africa (secondary focus). 2. Identify, validate, and genetically map phenotypic traits conferring phosphorus acquisition efficiency in beans. 3. Evaluate bean breeding lines for Mn tolerance.
