Andrade, M.I.Alvaro, A.Menomussanga, J.Makunde, G.S.Ricardo, J.Gruneberg, W.J.Eyzaguirre, R.Low, J.W.Ortiz, R.['Alisha', 'Anamaria', 'Bie', 'Bita', 'Caelan', 'Ivone', 'Lawrence', 'Margarete', and 'Victoria' sweetpotato.]'Alisha', 'Anamaria', 'Bie', 'Bita', 'Caelan', 'Ivone', 'Lawrence', 'Margarete', and 'Victoria' sweetpotato.

Optimisation of sweetpotato production potential is not realized in sub-Saharan Africa where dry spells are common after the growing season. Lack of seed cultivars at the beginning of the rainy season is the challenge and identifying those cultivars with the ability to survive a 4 to 7-month dry ...


Andrade, M.I.Makunde, G.S.Ricardo, J.Menomussanga, J.Alvaro, A.Gruneberg, W.J.[Survival of sweetpotato (Ipomoea batatas [L] Lam) vines in cultivars subjected to long dry spells after the growing season in Mozambique]Survival of sweetpotato (Ipomoea batatas [L] Lam) vines in cultivars subjected to long dry spells after the growing season in Mozambique

Long-term storage of sweetpotato roots is a great challenge for smallholder farmers in Mozambique. Piecemeal harvesting allows several months supply of roots for household consumption provided weevil infestation is avoided. The objectives of the present studies were to determine yield and changes...


Alvaro, A.Andrade, M.I.Makunde, G.S.Dango, F.Idowu, O.Gruneberg, W.J.[Yield, nutritional quality and stability of orangefleshed sweetpotato cultivars successively later harvesting periods in Mozambique]Yield, nutritional quality and stability of orangefleshed sweetpotato cultivars successively later harvesting periods in Mozambique

The amount of genotypic and phenotypic variability that exists in a species is important for selection and initiating breeding programs. Yam bean is grown locally in tropical countries of the Americas and Asia for their tasty storage roots, which usually have low dry matter content. The crop was ...


Agaba, R.Tukamuhabwa, PhinehasRubaihayo, P.R.Tumwegamire, SilverSsenyonjo, A.Mwanga, R.O.M.Ndirigwe, J.Gruneberg, W.J.[Genetic variability for yield and nutritional quality in yam bean (Pachyrhizus sp.)]Genetic variability for yield and nutritional quality in yam bean (Pachyrhizus sp.)

El camote (Ipomoea batatas L) es el principal componente en la dieta de millones de personas que viven en países tropicales, y un mejoramiento en el contenido de â-caroteno podría incrementar el suministro de vitamina A para satisfacer la mayor parte de las necesidades diarias de la gente. En el ...


Carpio, R.Sotelo, A.Gruneberg, W.J.[Contenido de ß-caroteno, hierro y zinc, efecto de almacenamiento y tipo de cocción en genotipos de camote (Ipomoea batatas L)]Contenido de ß-caroteno, hierro y zinc, efecto de almacenamiento y tipo de cocción en genotipos de camote (Ipomoea batatas L)

African dry and starchy (DS) orange-fleshed sweetpotato [Ipomoea batatas (L.) Lam] (OFSP) cultivars, distinct from American moist or medium dry and sweet OFSP, have potential to fight vitamin A deficiency (VAD) in the world. This study assessed the genotype × environment (G × E) interactions in m...


Tumwegamire, SilverRubaihayo, P.R.Gruneberg, W.J.LaBonte, D.R.Mwanga, R.O.M.Kapinga, R.[Genotype x environment interactions for East African orange-fleshed sweetpotato clones evaluated across varying ecogeographic conditions in Uganda]Genotype x environment interactions for East African orange-fleshed sweetpotato clones evaluated across varying ecogeographic conditions in Uganda

Sweetpotato breeding requires at least 5 years to obtain an advanced breeding clone for further testing with the goal of cultivar release. An accelerated breeding scheme (ABS) can be feasible if the genotype × year interaction is low. The objectives of the present study were to describe an ABS fo...


Andrade, M.I.Ricardo, J.Naico, A.Alvaro, A.Makunde, G.S.Low, J.W.Ortiz, J.Gruneberg, W.J.[Release of orange-fleshed sweetpotato (Ipomoea batatas [l.] Lam.) cultivars in Mozambique through an accelerated breeding scheme.]Release of orange-fleshed sweetpotato (Ipomoea batatas [l.] Lam.) cultivars in Mozambique through an accelerated breeding scheme.

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.

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 ...
