A combination of joint linkage and genome-wide association study reveals putative candidate genes associated with resistance to northern corn leaf blight in tropical maize por Ndlovu, Noel, Gowda, Manje, Beyene, Yoseph, Das, Biswanath, Mahabaleswara, Suresh L., Makumbi, Dan, Ogugo, Veronica, Burgueño, Juan, Crossa, Jose, Spillane, Charles, McKeown, Peter C., Brychkova, Galina, Prasanna, Boddupalli M.

“…Genome-wide predictions revealed moderate correlations with mean values of 0.45, 0.44, 0.55, and 0.42 for within GWAS panel, DH pop1, DH pop2, and DH pop3, respectively. Prediction by incorporating marker-by-environment interactions did not show much improvement. …”

Genetic variances and relationship among traits of an early maturing maize population under drought-stress and low nitrogen environments por Talabi, A.O., Badu-Apraku, Baffour, Fakorede, M.A.B.

“…Drought and low soil nitrogen (low N) are major causes of low grain yield of maize (Zea mays L.) in sub-Saharan Africa (SSA). An early maturing maize population, TZE-Y Pop DT STR, had undergone four cycles of selection for drought tolerance, followed by four selection cycles for resistance to Striga hermonthica (Del.) …”

Genetic variances and heritabilities of early yellow maize population following cycles of improvement for Striga resistance and drought tolerance por Badu-Apraku, Baffour, Ifie, B.E., Talabi, A.O., Obeng-Bio, E., Asiedu, Robert

“…Drought and Striga are principal constraints to maize production in sub-Saharan Africa. An early yellow maize population, TZE-Y Pop DT STR that had undergone five cycles of selection for resistance to Striga, followed by three cycles of improvement for drought tolerance was investigated for yield gains, changes in genetic variances and interrelationships among traits under drought-stress and optimum environments. …”

Genetic studies of extra-early provitamin-A maize inbred lines and their hybrids in multiple environments por Badu-Apraku, Baffour, Fakorede, M.A.B., Talabi, A.O., Oyekunle, M., Aderounmu, M., Lum, A.F., Ribeiro, P.F., Adu, G.B., Toyinbo, J.O.

“…Vitamin A deficiency, drought, low soil nitrogen (low N) and Striga hermonthica parasitism of maize (Zea mays L.) cause malnutrition and food insecurity in sub-Saharan Africa. The objectives of this study were to determine combining abilities of extra-early provitamin A (PVA) lines, classify them into heterotic groups (HGs), identify testers, and determine yield stability of hybrids under contrasting environments in two trials. …”
