Technical Abstract: The largest soybean producer in Africa is Nigeria where 484,000 MT were produced in 680,000 ha in 2003. From 1994 and 1998, Nigeria dramatically increased soybean hectares (up by 225%) and production (up by 250%). Adoption of improved high-yielding cultivars and good management practices coupled with better marketability contributed to the upsurge of soybean in Nigeria. Soybean rust was first observed in 1999 and is now endemic and causing serious losses in Nigeria. Nearly all released cultivars and elite breeding materials in final stages of testing are highly susceptible to the rust fungus Phakopsora pachyrhizi. The soybean research program at IITA urgently emphasizes the development of rust resistant cultivars for African farmers.
