Adebayo, M.A.Menkir, A.Gedil, M.Blay, E.Gracen, V.E.Danquah, E.Y.Funmilayo, L.[Diversity assessment of drought tolerant exotic and adapted maize (Zea mays L.) inbred lines with microsatellite markers]Diversity assessment of drought tolerant exotic and adapted maize (Zea mays L.) inbred lines with microsatellite markers

Low soil Nitrogen (low-N) is one of the most important abiotic stresses responsible for significant yield losses in maize (Zea mays. L.). The development and commercialization of low N tolerant genotypes can contribute to improved food security in developing countries. However, selection for low ...


Ribeiro, P.F.Badu-Apraku, B.Gracen, V.E.Danquah, E.Y.García Oliveira, A.L.Asante, M.D.Afriyie-Debrah, CharlesGedil, M.[Identification of QTLs for grain yield and other traits in tropical maize under high and low soil-nitrogen environments.]Identification of QTLs for grain yield and other traits in tropical maize under high and low soil-nitrogen environments.

The development of hybrids with enhanced expression of heterosis depends on the genetic background of the source population and the effectiveness of a breeding scheme used to identify and use divergent inbred lines with good combining ability. The present study was conducted to examine the potent...


Menkir, A.Kling, J.G.Anjorin, B.Ladejobi, F.Gedil, M.[Evaluating testcross performance and genetic divergence of lines derived from reciprocal tropical maize composites]Evaluating testcross performance and genetic divergence of lines derived from reciprocal tropical maize composites

The discovery and use of genetic markers associated with carotenoid levels can help to exploit the genetic potential of maize for provitamin A accumulation more effectively. Provitamin A carotenoids are classes of carotenoids that are precursors of vitamin A, an essential micronutrient in humans....


Azmach, G.Menkir, A.Spilane, C.Gedil, M.[Genetic loci controlling carotenoid biosynthesis in diverse tropical maize lines]Genetic loci controlling carotenoid biosynthesis in diverse tropical maize lines

Maize production in West and Central Africa (WCA) is constrained by a wide range of interacting stresses that keep productivity below potential yields. Among the many problems afflicting maize production in WCA, drought, foliar diseases, and parasitic weeds are the most critical. Several decades ...


Gedil, M.Menkir, A.[An integrated molecular and conventional breeding scheme for enhancing genetic gain in maize in Africa]An integrated molecular and conventional breeding scheme for enhancing genetic gain in maize in Africa

The study aimed at examining the associations between yield and other traits under drought stress and non-stress conditions. A total of 150 MARS testcrosses were evaluated under both conditions at the International Institute of Tropical Agriculture substation for two years under during the dry se...


Bankole, F.Menkir, A.Olaoye, G.Olakojo, O.Gedil, M.[Association studies between grain yield and agronomic traits of a MARS maize (Zea mays L.) population under drought and non-stress condition]Association studies between grain yield and agronomic traits of a MARS maize (Zea mays L.) population under drought and non-stress condition

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

Molecular-based characterization of open-pollinated varieties (OPVs) in maize is useful to define their unique profiles. A total of 58 SSR markers selected from a panel of 70 were used for genotyping three samples of 30, 50 and 100 plant bulks for each of 32 OPVs. The SSR markers detected a total...


Arafayne, G.Menkir, A.Adetimirin, V.O.Gedil, M.[Optimizing sample size for molecular characterization of open-pollinated maize (Zea mays L.) varieties using simple sequence repeat markers]Optimizing sample size for molecular characterization of open-pollinated maize (Zea mays L.) varieties using simple sequence repeat markers

Marker-assisted recurrent selection (MARS) is a breeding method used to accumulate favorable alleles that for example confer tolerance to drought in inbred lines from several genomic regions within a single population. A bi-parental cross formed from two parents that combine resistance to Striga ...


Abdulmalik, R.O.Menkir, A.Meseka, S.K.Unachukwu, N.N.Ado, S.G.Olarewaju, J.D.Aba, D.A.Hearne, S.Crossa, J.Gedil, M.[Genetic gains in grain yield of a maize population improved through marker assisted recurrent selection under stress and non-stress conditions in west Africa]Genetic gains in grain yield of a maize population improved through marker assisted recurrent selection under stress and non-stress conditions in west Africa

The objective of marker assisted recurrent selection (MARS) is to increase the frequency of favorable marker alleles in a population before inbred line extraction. This approach was used to improve drought tolerance and grain yield (GY) in a biparental cross of two elite drought tolerant lines. T...


Bankole, F.Menkir, A.Olaoye, G.Crossa, J.Hearne, S.Unachukwu, N.N.Gedil, M.[Genetic gains in yield and yield related traits under drought stress and favorable environments in a maize population improved using marker assisted recurrent selection]Genetic gains in yield and yield related traits under drought stress and favorable environments in a maize population improved using marker assisted recurrent selection
