Sweet Potato Virus Diseases (SPVD) are an important biotic constraint to sweet potato production in parts of East Africa. Technologies consisting of participatory selection procedures and an Integrated Pest Management (IPM) package were developed to improve the performance and farmer-acceptability of locally selected sweet potato clones resistant to SPVD. These have been validated in Uganda and Tanzania. Procedures were established to improve planting materials and to make them more widely available via the International Potato Center (CIP) network in East Africa.
