Badu-Apraku, B.Yallou, C.Oyekunle, M.Akinwale, R.Aweke, G.Kamara, A.[Consistency of performance of early-maturing maize cultivars in Striga infested and Striga-free environments]Consistency of performance of early-maturing maize cultivars in Striga infested and Striga-free environments

Drought occurrence and striga hermonthica (Del.) Benth infestation are formidable maize (Zea mays L.) production constriants in the savanna zones of West and Central Africa (WCA). The West and Central Africa collaborative Maize Research Network (WECAMAN), in collaboration with the International I...


Badu-Apraku, B.Fakorede, M.A.B.Menkir, A.Kamara, A.Y.Akanvou, L.Chabi, Y.[Response of early maturing maize to multiplestresses in the Guinea savanna of West and Central Africa]Response of early maturing maize to multiplestresses in the Guinea savanna of West and Central Africa

The magnitude and type of genetic variability are of prime importance to breeders in determining whether or not to improve a breeding population and the method to use. The early maturing population, TZE-W Pop DT STR, has gone through three cycles of S1 recurrent selection for improvement for grai...


Badu-Apraku, B.[Genetic variances and correlations in an early tropical white maize population after three cycles of recurrent selection for Striga resistance]Genetic variances and correlations in an early tropical white maize population after three cycles of recurrent selection for Striga resistance

Striga hermonthica is a major constraint to maize (Zea mays L.) production in sub-Saharan Africa. The use of secondary traits that have high heritability and genetic correlation with grain yield can improve the precision with which Striga resistant genotypes are identified. Fifteen early cultivar...


Badu-Apraku, B.Akinwale, R.[Cultivar evaluation and trait analysis of tropical early maturing maize under Strigainfested and Strigafree environments]Cultivar evaluation and trait analysis of tropical early maturing maize under Strigainfested and Strigafree environments

Maize (Zea mays L.) hybrids resistant to Striga hermonthica (Del) Benth and tolerant to drought are vital to the sustainability of productivity of the maize-based farming systems of West and Central Africa (WCA). Thirty-six diallel crosses derived from nine early maturing white maize inbreds were...


Badu-Apraku, B.Oyekunle, M.Akinwale, R.O.Lum, A.F.[Combining ability of earlymaturing white maize inbreds under stress and nonstress environments]Combining ability of earlymaturing white maize inbreds under stress and nonstress environments

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

Emergence of several seed companies in the West Africa sub-region during the last decade has necessitated intensified efforts towards hybrid development and extensive testing. The objectives of the present study were to evaluate selected Striga-resistant maize (Zea mays L.) hybrids for grain yiel...


Akinwale, R.Badu-Apraku, B.Fakorede, M.A.B.[Evaluation of strigaresistant early maize hybrids and test locations under strigainfested and strigafree environments]Evaluation of strigaresistant early maize hybrids and test locations under strigainfested and strigafree environments

Maize (Zea mays L.) has the greatest yield potential in savannas of West and Central Africa (WCA). However, production in this agroecology is constrained by low levels of N, drought, and parasitism by striga [Striga hermonthica (Del) Benth.]. Diallel crosses involving 17 extra-early white maize i...


Badu-Apraku, B.Oyekunle, M.Akinwale, R.Aderounmu, R.O.[Combining ability and genetic diversity of extraearly white maize inbreds under stress and nonstress environments]Combining ability and genetic diversity of extraearly white maize inbreds under stress and nonstress environments

Striga represents the largest biological threat to cereal production in sub-Saharan Africa. Breeding for resistance to Striga has been the focal point of IITA to reduce the impact of this parasite on maize production. The early breeding work at IITA focused on search for tolerance to Striga. IITA...


Menkir, A.Kling, J.G.Badu-Apraku, B.The, C.Ibikunle, O.[Recent advances in breeding maize for resistance to Striga hermonthica (Del.) Benth]Recent advances in breeding maize for resistance to Striga hermonthica (Del.) Benth

Drought is a major constraint to maize production in West and Central Africa (WCA). Assessment of genetic gain from S1 recurrent selection under drought is crucial for the development of drought tolerance breeding strategies. In an early white population, 60 S1 families each derived from the base...


Badu-Apraku, B.Oyekunle, M.Talabi, A.O.Annor, B.Akaogu, I.C.[Changes in genetic variances and heritabilities in an early white maize population following S1 selection for grain yield, Striga resistance and drought tolerance]Changes in genetic variances and heritabilities in an early white maize population following S1 selection for grain yield, Striga resistance and drought tolerance
