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

Two improved tropical maize composites, TZL COMP3 and TZL COMP4; representing complementary heterotic pools have been subjected to four cycles of reciprocal recurrent selection (RRS) for two decades to enhance varietal cross performance. The objectives of this study were to evaluate the effect of...


Kolawole, A.O.Menkir, A.Blay, E.Ofori, K.Kling, J.G.[Changes in heterosis of maize (Zea mays L.) varietal cross hybrids after four cycles of reciprocal recurrent selection]Changes in heterosis of maize (Zea mays L.) varietal cross hybrids after four cycles of reciprocal recurrent selection

Assessment of genetic gain in two tropical maize (Zea mays L.) composites improved across years is critical in determining their future improvement and use as sources of inbred lines. Two genetically complementary tropical maize composites were subjected to four cycles of reciprocal recurrent sel...


Kolawole, A.O.Menkir, A.Blay, E.Ofori, K.Kling, J.[Genetic advance in grain yield and other traits in two tropical maize composites developed via reciprocal recurrent selection]Genetic advance in grain yield and other traits in two tropical maize composites developed via reciprocal recurrent selection

Abstract Introduced maize (Zea mays L.) germplasmcan serve as sources of favorable alleles toenhance performance in new maize varieties andhybrids under drought stress conditions. In the presentstudy, the combining abilities of 12 exotic maizeinbred lines from CIMMYT and 12 adapted maizeinbred li...


Adebayo, M.A.Menkir, A.Blay, E.Gracen, V.E.Danquah, E.Y.Hearne, S.[Genetic analysis of drought tolerance in adapted X exotic crosses of maize inbred lines under managed stress conditions]Genetic analysis of drought tolerance in adapted X exotic crosses of maize inbred lines under managed stress conditions

Cassava green mite [CGM, Mononychellus tanajoa (Bondar)] is a dry-season pest that usually feeds on the underside of young leaves causing leaf chlorosis, stunted growth, and root yield reduction by 80%. Since cassava (Manihot esculenta Crantz) leaves and roots serve as a primary staple food sourc...


Ezenwaka, L.C.Carpio, D.P. delJannink, Jean-LucRabbi, Ismail Y.Danquah, E.Y.Asante, I.Danquah, A.Blay, E.Egesi, Chiedozie N.[Genome-wide association study of resistance to cassava green mite pest and related traits in cassava]Genome-wide association study of resistance to cassava green mite pest and related traits in cassava

The goal of most rice improvement programs is the enhancement of farmers' yield using less land and limited water. This study evaluated 77 upland rice genotypes under optimal upland growing conditions in the field and ranked the genotypes using base indices. Subsequently, eighteen cultivars selec...

Knowledge of the heterotic responses of elite adapted and exotic maize inbred lines can facilitate their utilization for population improvement and hybrid development. In the present study, a line x tester mating design was used to determine the combining ability of 20 elite drought-tolerant maiz...

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...
