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 IPM package were developed to improve the performance and farmer-acceptability of locally selected sweet potato clones resistant to SPVD, and these have been validated in Uganda and Tanzania. Procedures were put in place for improved planting materials to be made more widely available via the CIP network in East Africa.
