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

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

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...


Adebayo, A.Menkir, A.Blay, E.Gracen, V.E.Danquah, E.Y.[Performance based grouping of adapted and exotic drought tolerant maize (Zea mays L) inbred lines under stressed and nonstressed conditions]Performance based grouping of adapted and exotic drought tolerant maize (Zea mays L) inbred lines under stressed and nonstressed conditions

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

Estimates of combining abilities and heterosis of inbred lines are imperative for selection of suitable parents of maize hybrids. This study examined the combining ability of 24 drought-tolerant maize inbred lines, 12 each from International Centre for Maize and Wheat Improvement (CIMMYT) and Int...
