Vitamin A deficiency, drought, low soil nitrogen (low N) and Striga hermonthica parasitism of maize (Zea mays L.) cause malnutrition and food insecurity in sub-Saharan Africa. The objectives of this study were to determine combining abilities of extra-early provitamin A (PVA) lines, classify them...


Badu-Apraku, B.Fakorede, M.A.B.Talabi, A.O.Oyekunle, M.Aderounmu, M.Lum, A.F.Ribeiro, P.F.Adu, G.B.Toyinbo, J.O.[Genetic studies of extra-early provitamin-A maize inbred lines and their hybrids in multiple environments]Genetic studies of extra-early provitamin-A maize inbred lines and their hybrids in multiple environments

Maize (Zea mays L.) cultivars combining high grain yield with elevated levels of lysine, tryptophan, and desirable endosperm modification, could reduce food insecurity and malnutrition in West and Central Africa (WCA). Sixteen early- and nine extra-early-maturing quality protein maize (QPM) and n...

Striga and drought are major constraints to maize (Zea mays L.) production in the savannas of west and central Africa (WCA). A study was conducted in 2005 and 2006 in Nigeria to determine the level of resistance to Striga hermonthica for two early-maturing maize populations, one white and one yel...

Maize (Zea mays L.) production in west and central Africa (WCA) is constrained by the parasitic weed Striga hermonthica (Del.) Benth and recurrent drought. Two early maize populations, TZE-W Pop DT STR C0 (white) and TZE-Y Pop DT STR C0 (yellow), developed from diverse genetic backgrounds, were s...


Badu-Apraku, B.Lum, A.F.Fakorede, M.A.B.Menkir, A.Chabi, Y.The, C.Abdulai, M.Jacob, S.Agbaje, S.[Performance of early maize cultivars derived from recurrent selection for grain yield and Striga resistance]Performance of early maize cultivars derived from recurrent selection for grain yield and Striga resistance

The potential maize (Zea mays L.) yield in the savannas of West and Central Africa (WCA) is constrained by Striga hermonthica (Del.) Benth. parasitism. Field trials at Ferkessedougou, Côte d'Ivoire; Abuja, Nigeria; and Mokwa, Nigeria, in 2002, and at Mokwa and Abuja in 2004, evaluated the perform...


Badu-Apraku, B.Lum, A.F.[Agronomic performance of striga resistant early-maturing maize varieties and inbred lines in the savannas of West and Central Africa]Agronomic performance of striga resistant early-maturing maize varieties and inbred lines in the savannas of West and Central Africa
