Semagn, K.Ndjiondjop, Marie-NoelLorieux, MCissoko, M.Jones, M.McCouch, Susan R.[Molecular profiling of an interspecific rice population derived from a cross between WAB 56-104 (Oryza sativa) and CG 14 (Oryza glaberrima)]Molecular profiling of an interspecific rice population derived from a cross between WAB 56-104 (Oryza sativa) and CG 14 (Oryza glaberrima)

Molecular characterization is important for efficient utilization of germplasm and development of improved varieties. In the present study, we investigated the genetic purity, relatedness and population structure of 265 maize inbred lines from the Ethiopian Institute of Agricultural Research (EIA...

Previous studies conducted on limited number of accessions have reported very low genetic variation in African rice (Oryza glaberrima Steud.) as compared to its wild progenitor (O. barthii A. Chev.) and to Asian rice (O. sativa L.). Here, we characterized a large collection of African rice and co...


Ndjiondjop, M.N.Alachiotis, N.Pavlidis, P.Goungoulou, A.Kpeki, S.B.Zhao, D.Semagn, K.[Comparisons of molecular diversity indices, selective sweeps and population structure of African rice with its wild progenitor and Asian rice]Comparisons of molecular diversity indices, selective sweeps and population structure of African rice with its wild progenitor and Asian rice

Using interspecific crosses involving Oryza glaberrima Steud. as donor and O. sativa L. as recurrent parents, rice breeders at the Africa Rice Center developed several 'New Rice for Africa (NERICA)' improved varieties. A smaller number of interspecific and intraspecific varieties have also been r...


Ndjiondjop, M.N.Semagn, K.Sow, M.Manneh, B.Gouda, A.C.Kpeki, S.B.Pegalepo, E.Wambugu, P.Sié, M.Warburton, M.L.[Assessment of Genetic Variation and Population Structure of Diverse Rice Genotypes Adapted to Lowland and Upland Ecologies in Africa Using SNPs]Assessment of Genetic Variation and Population Structure of Diverse Rice Genotypes Adapted to Lowland and Upland Ecologies in Africa Using SNPs

Species misclassification (misidentification) and handling errors have been frequently reported in various plant species conserved at diverse gene banks, which could restrict use of germplasm for correct purpose. The objectives of the present study were to (i) determine the extent of genotyping e...


Ndjiondjop, M.N.Semagn, K.Zhang, J.Gouda, A.C.Kpeki, S.B.Goungoulou, A.Wambugu, P.Dramé, K.N.Bimpong, I.K.Zhao, D.[Development of species diagnostic SNP markers for quality control genotyping in four rice (Oryza L.) species]Development of species diagnostic SNP markers for quality control genotyping in four rice (Oryza L.) species

Abstract Maize streak virus (MSV) disease is a devastating disease in the Sub-Saharan Africa (SSA), which causes significant yield loss in maize. Resistance to MSV has previously been mapped to a major QTL (Msv1) on chromosome 1 that is germplasm and environment independent and to several minor l...

African rice gall midge (AfRGM) is one of the most destructive pests of irrigated and lowland African ecologies. This study aimed to identify the quantitative trait loci (QTL) associated with AfRGM pest incidence and resistance in three independent bi-parental rice populations (ITA306xBW348-1, IT...
