Summary for Project title: R8040: Rapid multiplication and distribution of sweet potato varieties with high yielding and B-carotene content.

Sweet potato growers in Uganda have gone from not having enough product to eat, to wondering how best to market all the sweet potatoes they harvest. Previously, vines for planting sweet potato crops were in extremely short supply. Plus, sweet potato virus severely damaged tubers. Now, farmer groups produce and market plenty of quality planting material—varieties resistant to virus disease. The new sweet potatoes, high in beta-carotene, also help reduce serious vitamin A deficiencies which affect 30% of children and 50% of women. Quality sweet potatoes for export fetch high prices. A new growers association is already working to export the new varieties. The potential is huge and the improved varieties have spread to D.R. Congo, Kenya, Tanzania, Sudan and even Chad.
