Groundnuts play a key role as a subsistence food source for poor people in the districts in northeastern Uganda, where the “Teso” system of agriculture is practiced. The crop is a valuable source of protein and oil and thus makes a significant contribution to people’s nutritional requirements. With a decline in the production of traditional cash crops such as cotton, groundnuts are now also gaining increasing importance as a cash crop. A needs assessment, funded by DFID in February 1998, identified rosette disease as the most important general or pest and disease problem on groundnuts both by farmers and the Serere Agricultural and Animal Production Research Institute (SAARI). This technology describes ways in which community seed production of groundnut rosette-resistant varieties were promoted and out-scaled in Uganda, through farmer-led production groups.
