  1. Progress in Breeding Orange-fleshed Sweetpotato in sub-Saharan Africa Mwanga R., G. Ssemakula, B. Yada, J. Kreuze, S. Fuentes, J. Low, W. Grüneberg, E. Carey, M. Andrade, E. Lukonge, B. Kivuva, J. Ndirigwe, C. Yencho Planet Earth Institute Spotlight Seminar: The Future of Agriculture in Africa The Library, Royal Society of Chemistry, Burlington House, London, UK March 15, 2017 The Sweetpotato Action for Security and Healthin Africa (SASHA) is a five-year initiative designed to improve the food security and livelihoods of poor families in Sub-Saharan Africa by exploiting the untapped potential of sweetpotato. It will develop the essential capacities, products, and methods to reposition sweetpotato in food economies of Sub-Saharan African countries to alleviate poverty and under-nutrition. SWEETPOTATO ACTION FOR SECURITY AND HEALTH IN AFRICA

  2. Outline of presentation • Background, yield losses due to sweetpotato virus disease (SPVD) • Old sweetpotato breeding cycle • Breeding for beta-carotene (orange flesh) • Progress to date

  3. Sweetpotato Virus Disease (SPVD) Causes Significant Yield Losses (50->90%) (drought?) Clark et al. 2012: Plant Disease

  4. Developing populations for SPVD resistance and quality traits

  5. Regional genotype x environment orange-fleshed sweetpotato trials, 15 Trial Sites 2006/2007 Serere Namulonge Kacwekano . . . . . Kakamega . . Bukoba . Zanzibar Kizimbani Hombolo . . Kibaha Angoni . Rubona Kibundu . Gurue . Mandoto Mimosa Umbelezi Not to scale

  6. Sweetpotato seed sent from Uganda to SSA Countries in 2007/2008 (Total amount of seed: 471,405) 20,320 . . . . 10,540 . . . 152,640 . 32,850 37,350 90,400 . 71,010 17,590 . 21,000 8,000 . Not to scale 9,705

  7. Variety Selection/Breeding Combine high beta-carotene with other major desirable traits -

  8. Sweetpotato Action for Security and Health in Africa (SASHA) – from 2009 supported sweetpotato platforms

  9. African sweetpotato breeders breed in Africa for Africa using the latest knowledge and efficient methods Since 2009 nine countries have released 56 new superior varieties; 40 of them orange-fleshed 12 Countries with crossing blocks/breeding 3 Countries with sweetpotato evaluation/ selection activities
