Across both regions a close correlation between rainfall and maize production can be observed. In collaboration with National Agricultural Research Programmes and regional organizations (ASARECA, SACCAR), CIMMYT has initiated in 1996 and 1998 two projects that provide NARS with technical and financial support to develop maize germplasm that is more tolerant to drought and N deficiency. Over 100 scientists and technicians have benefited from training opportunities, and capital and recurrent support has been given to stress breeding and testing programmes in ten southern and nine eastern African countries. Several of these breeding programmes have produced stress tolerant experimental OPVs and hybrids that now enter the testing phase. Trials conducted by researchers across the regions, and farmer-participatory trials conducted in collaboration with NGO's. extension and farmer groups have been established to expose the merit of these new varieties under stress conditions that are typical for most smallholder farmers. Even though the breeding approach taken with these two projects seems new to most breeders in Africa, it agrees with research findings from other crop breeding programmes that target stress-prone environments. The fact that farmers as well as private and non-governmental organizations involved in seed dissemination have shown a rapid response to some of the new varieties confirms the merit of these two projects for contributing to food security and economic growth in Africa.Collection: CIMMYT Staff Publications Collection
