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

Understanding the nature and extent of association between yield and yield related traits is the prerequisite study for any underutilized crop improvements of sustainable genetic enhancement. However, there is a lack of sufficient information on seed yield and related trait correlation and path c...


Walle, T.Mekbib, F.Amsalu, B.Gedil, M.[Correlation and path coefficient analyses of cowpea (Vigna unguiculata L.) landraces in Ethiopia]Correlation and path coefficient analyses of cowpea (Vigna unguiculata L.) landraces in Ethiopia

The extent of genetic diversity and relatedness of cowpea germplasm from East Africa are poorly understood. A set of 13 microsatellites (SSR) and 151 single nucleotide polymorphisms (SNPs) markers were applied to assess the levels of genetic diversity in a sample of 95 accessions of local cowpea ...


Desalegne, B.A.Dagne, K.Gedil, M.Boukar, O.Fatokun, C.A.[Efficiency of SNP and SSR-based analysis of genetic diversity, population structure, and relationships among cowpea (Vigna unguiculata (L.) Walp.) germplasm from east Africa and IITA inbred lines]Efficiency of SNP and SSR-based analysis of genetic diversity, population structure, and relationships among cowpea (Vigna unguiculata (L.) Walp.) germplasm from east Africa and IITA inbred lines

Cassava anthracnose disease (CAD) is a major stem disease of cassava (Manihot esculenta Crantz) in the cassava growing areas of the world. To identify markers associated with resistance to CAD, F1 progenies were produced from a cross between resistant genotype TME 117, and susceptible genotype TM...


Akinbo, OlalekanGedil, M.Ekpo, E.J.A.Oladele, J.Dixon, Alfred G.O.[Detection of RAPD markers linked to resistance to cassava anthracnose disease]Detection of RAPD markers linked to resistance to cassava anthracnose disease

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

Cassava is a widely grown staple in Sub-Saharan Africa and consumed as a cheap source of calories, but the crop is deficient in micronutrients including pro-vitamin A carotenoids. This challenge is currently being addressed through biofortification breeding that relies on phenotypic selection. Ge...


Udoh, L.I.Gedil, M.Parkes, E.Y.Kulakow, P.A.Adesoye, A.I.Nwuba, C.Rabbi, Ismail Y.[Candidate gene sequencing and validation of SNP markers linked to carotenoid content in cassava (Manihot esculenta Crantz)]Candidate gene sequencing and validation of SNP markers linked to carotenoid content in cassava (Manihot esculenta Crantz)

Cross contamination arising from random natural processes and breeding errors is one of the prominent challenges to breeding in many crops including cassava (Manihot esculenta). This study attempts to identify molecular marker tools suitable for verifying the genetic purity of putative progenies ...


Otti, G.Fakoya, A.Andrew, I.Gedil, M.[Development of genomic tools for verification of hybrids and selfed progenies in cassava (Manihot esculenta)]Development of genomic tools for verification of hybrids and selfed progenies in cassava (Manihot esculenta)

Some genetic studies using molecular methods such as diversity assessment or marker-assisted selection require collection of a large number of samples from fields located in the vicinity or in remote areas, followed by isolation of good quality DNA in a short time span. In the present study, diff...


Bhattacharjee, R.Ferguson, M.Gedil, M.Dumet, D.Ingelbrecht, I.L.[Field collection,preservation and large scale DNA extraction procedures for cassava (Manihot esculenta Crantz.)]Field collection,preservation and large scale DNA extraction procedures for cassava (Manihot esculenta Crantz.)

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....
