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

Appropriate testers are needed as well as information on heterotic patterns of tropical lowland early-maturing germplasm. Diallel crosses involving nine tropical early maturing maize (Zea mays L.) inbreds were evaluated at five locations in Nigeria from 2007 to 2009 under drought stress, when Str...


Badu-Apraku, B.Fontem, Lum. A.Akinwale, R.Oyekunle, M.[Biplot analysis of diallel crosses of early maturing tropical yellow maize inbreds in stress and nonstress environments]Biplot analysis of diallel crosses of early maturing tropical yellow maize inbreds in stress and nonstress environments

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

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

A base index involving Striga damage, number of emerged Striga plantsand ears per plant is used for selecting for maize (Zea mays L.) grainyield under Striga infestation. There are contradictory reports on the reliabilityof number of emerged Striga plants for selecting for Striga resistance.The o...


Badu-Apraku, B.Akinwale, R.Oyekunle, M.[Efficiency of secondary traits in selecting for improved grain yield in extraearly maize under Strigainfested and Strigafree environments]Efficiency of secondary traits in selecting for improved grain yield in extraearly maize under Strigainfested and Strigafree environments

Badu-Apraku, B.Gedil, M.Fakorede, M.A.B.Akinwale, R.Fasanmade, Y.Annor, B.Talabi, A.O.Oyekunle, M.Akaogu, I.C.Aderounmu, M.[Gene action and heterotic groups of early white quality protein maize inbreds under multiple stress environments]Gene action and heterotic groups of early white quality protein maize inbreds under multiple stress environments

Extra-early maize (Zea mays L) tolerant to low-N and drought could stabilize yields in sub-Saharan Africa. Studies were conducted under drought and low-N conditions in Nigeria for three years to determine the potential of 90 extra-early inbreds for hybrid production and evaluate the performance o...


Badu-Apraku, B.Fakorede, M.A.B.Oyekunle MAkinwale, R.[Selection of extra-early maize inbreds under low N and drought at flowering and grain-filling for hybrid production]Selection of extra-early maize inbreds under low N and drought at flowering and grain-filling for hybrid production

Maize (Zea mays L.), an important staple crop in West and Central Africa (WCA), has enormous potential to reduce food insecurity in this subregion. Research covering three periods or eras of breeding has been conducted to develop cultivars resistant/tolerant to three maize stress factors: Striga ...


Badu-Apraku, B.Fakorede, M.A.B.Oyekunle, M.Yallou, G.C.Obeng-Antwi, K.Haruna, A.Usman, I.Akinwale, R.[Gains in grain yield of early maize cultivars developed during three breeding eras under multiple environments]Gains in grain yield of early maize cultivars developed during three breeding eras under multiple environments
Akinwale, R.Badu-Apraku, B.Fakorede, M.A.B.Vroh Bi, Irie[Heterotic grouping of tropical earlymaturing maize inbred lines based on combining ability in Strigainfested and Strigafree environments and the use of SSR markers for genotyping]Heterotic grouping of tropical earlymaturing maize inbred lines based on combining ability in Strigainfested and Strigafree environments and the use of SSR markers for genotyping
