Zambia has continued to experience drought conditions since the worst drought in recent times, 1991/92 season. The National Maize Research Programme, in collaboration with the CIMMYT Regional Project, "Increasing the Tolerance of Maize in Southern Africa to Drought and Low Soil Fertility," based in Zimbabwe, has been involved in the development of drought tolerant varieties since 1996. Methods developed at CIMMYT-Mexico of developing stress tolerant maize have been employed and are being replicated in southern Africa and other regions of Africa (Banziger et al., 2002; Bolanos and Edmeades, 1996).
