Seed is the foundation for the production of cereals and grain legumes that underpins farm family food security and income across Africa and Asia. Throughout Africa, in particular, farmers themselves produce an estimated 80–100% of the seed of both local and improved varieties. A recognition of the centrality of farmer-managed seed suggests that research and development practitioners need to support this important system and seed source. Farmers typically produce seed and grain in the same field, although there can be wide variation between crops and cropping systems. Methods for seed selection also vary, as seed might be selected in the field or after harvest, or from stored grain only at the time of planting.
