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

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

Cowpea is a multipurpose pulse crop grown by poor farmers in marginal and drought prone areas of Ethiopia. Information on the extent of genetic variation in cowpea genotypes is crucial to identify diverse genotypes for crop improvement and for efficient utilization of the existing genetic resourc...


Walle, T.Mekbib, F.Amsalu, B.Gedil, M.[Genetic diversity of Ethiopian cowpea [Vigna unguiculata (L) Walp] genotypes using multivariate analyses]Genetic diversity of Ethiopian cowpea [Vigna unguiculata (L) Walp] genotypes using multivariate analyses

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...

Striga hermonthica and drought are the major stresses limiting maize yields in sub-Saharan Africa. The search for diverse maize lines’ tolerance to drought and resistance to S. hermonthica (DTSTHR) is very crucial for yield improvement in areas affected by the two stresses. Understanding the gene...


Mengesha, W.Menkir, A.Unachukwu, N.N.Meseka, S.K.Farinola, A.Girma Tessema, G.Gedil, M.[Genetic diversity of tropical maize inbred lines combining resistance to Striga hermonthica with drought tolerance using SNP markers]Genetic diversity of tropical maize inbred lines combining resistance to Striga hermonthica with drought tolerance using SNP markers

The extent of genetic diversity and genetic structure of 23 lowland and 23 mid-altitude adapted maize inbred lines that share a common source of resistance to the maize streak virus were surveyed using 18 amplified fragment length polymorphism (AFLP) primer pairs. Close to 86% of the 820 AFLP fra...


Menkir, A.Gedil, M.Franco, J.[Analysis of genetic structure and diversity among lowland and midaltitude adapted maize inbred lines with AFLP markers]Analysis of genetic structure and diversity among lowland and midaltitude adapted maize inbred lines with AFLP markers

Molecular-marker-aided evaluation of germplasm plays an important role indefining the genetic diversity of plant genotypes for genetic and populationimprovement studies. A collection of African cassava landraces and elite culti-vars was analysed for genetic diversity using 20 amplified fragment l...


Raji, A.A.J.Fawole, I.Gedil, M.Dixon, Alfred G.O.[Genetic differentiation analysis of African cassava (Manihot esculenta) landraces and elite germplasm using amplified fragment length polymorphism and simple sequence repeat markers]Genetic differentiation analysis of African cassava (Manihot esculenta) landraces and elite germplasm using amplified fragment length polymorphism and simple sequence repeat markers

Striga hermonthica is a parasitic weed that poses a serious threat to the production of economically important cereals in sub-Saharan Africa. The existence of genetic diversity within and between S. hermonthica populations presents a challenge to the successful development and deployment of effec...


Unachukwu, N.N.Menkir, A.Rabbi, Ismail Y.Oluoch, M.Muranaka, S.Elzein, A.Odhiambo, G.Farombi, E.O.Gedil, M.[Genetic diversity and population structure of Striga hermonthica populations from Kenya and Nigeria]Genetic diversity and population structure of Striga hermonthica populations from Kenya and Nigeria

Two tropical maize composites were subjected to four cycles of reciprocal recurrent selection to develop divergent inbred lines with good combining ability. This study was conducted to examine the extent of genetic diversity, changes in allele composition and genetic structure, of 100 randomly se...


Kolawole, A.O.Menkir, A.Gedil, M.Blay, E.Ofori, K.Kling, J.G.[Genetic divergence in two tropical maize composites after four cycles of reciprocal recurrent selection]Genetic divergence in two tropical maize composites after four cycles of reciprocal recurrent selection
