Lam germplasm.]Evaluation of dry matter, protein, starch, sucrose, <beta>-carotene, iron, zinc, calcium, and magnesium in East African sweetpotato [Ipomoea batatas (L.) Lam germplasm.
Mwanga, R.O.M.Ssemakula, G.N.[Orange-fleshed sweetpotatoes for food, health and wealth in Uganda.]Orange-fleshed sweetpotatoes for food, health and wealth in Uganda.

The development of innovative rice products is a way to exploiting and adding value to low-grade African rice varieties. To this purpose, rice-based pasta was enriched with flours from soybean and orange-fleshed sweet potato, that are common ingredients in the African tradition. Four different fo...


Marengo, M.Amoah, I.Carpen, A.Benedetti, S.Zanoletti, M.Buratti, S.Lutterodt, H.E.Johnson, P.T.Manful, J.Marti, A. Bonomi, F.Iametti, S.[Enriching gluten-free rice pasta with soybean and sweet potato flours]Enriching gluten-free rice pasta with soybean and sweet potato flours

Sweetpotato [Ipomoea batatas (L.) Lam] breeding is important for food security and health in East Africa (EA), and a breeding platform in Uganda provides national researchers and breeders in EA with true seed. Our objectives were to characterize genetic relationships among parental material used ...


David, M.C.Díaz, F.C.Mwanga, R.O.M.Tumwegamire, SilverMansilla, R.C.Gruneberg, W.J.[Gene pool subdivision of east African sweetpotato parental material]Gene pool subdivision of east African sweetpotato parental material

Embryo-like structures were induced from ‘whole leaf’ explants of sixteen of the twenty investigated sweet potato cultivars on Murashige and Skoog (1962) medium supplemented with 2,4 Dichlorophenoxyacetic acid (0.2 mg/L) at the Makerere University Agricultural Research Institute Tissue culture la...


Sefasi, A.Ghislain, M.Kiggundu, R.Ssemakula, G.N.Rukarwa, R.Kreuze, J.F.Mukasa, S.Mwanga, R.O.M.[Embryo-like structures and root regeneration induced by 2, 4-dichlorophenoxyacetic acid in twenty African sweet potato cultivars.]Embryo-like structures and root regeneration induced by 2, 4-dichlorophenoxyacetic acid in twenty African sweet potato cultivars.

This study used a field experiment and the means-end chain approach to examine the effect of providing information on the biofortification process on consumers' acceptance of orange-fleshed sweetpotato (OFSP). Negative, positive, and neutral information about the biofortification were verbally pr...


Okello, J.J.Lagerkvist, C.J.Muoki, P.Heck, S.Prain, G.[Does information on food production technology affect consumers' acceptance of biofortified foods? Evidence from a field experiment in Kenya.]Does information on food production technology affect consumers' acceptance of biofortified foods? Evidence from a field experiment in Kenya.

Curing in sweetpotato is a crucial pre- or postharvest practice that could guarantee improved shelf life,but rarely practised by sweetpotato farmers in Sub-Saharan Africa, principally due to lack of knowledge. Wound healing ability of cultivars has been associated with good root storability. In t...


Atuna, R.A.Carey, E.E.Low, J.W.Amagloh, F.K.[Wound healing and dry matter content of orange-fleshed sweetpotato cultivars as influenced by curing methods]Wound healing and dry matter content of orange-fleshed sweetpotato cultivars as influenced by curing methods

Biotic constraints cause major crop losses and, hence, food insecurity in sub-Saharan Africa. This study documented the popularity, production constraints, pests and diseases, farmers’ perceptions on the severity of biotic constraints and the impact of related crop losses on household food securi...


Okonya, J.Ocimati, W.Nduwayezu, A.Kantungeko, D.Niko, N.Blomme, GuyLegg, J.P.Kroschel, J.[Farmer reported pest and disease impacts on root, tuber, and banana crops and livelihoods in Rwanda and Burundi.]Farmer reported pest and disease impacts on root, tuber, and banana crops and livelihoods in Rwanda and Burundi.
