It is predominantly grown by smallholder farmers, but seed companies generally target large commercial farmers in high potential areas when developing new varieties. To address the needs of smallholder farmers in maize genetic improvement, the International Maize and Wheat Improvement Centre (CIMMYT) initiated a collaborative drought and low nitrogen maize breeding programme aimed to
