Low soil nitrogen (Low N), Striga hermonthica and recurrent drought are major constraints to maize production and productivity in sub-Saharan Africa (SSA). Only a few extra-early maturing hybrids with combined tolerance to drought, Striga and low N have been commercialized in SSA. The objectives ...
Four cycles of S1 family recurrent selection to improve grain yield and resistance to Striga hermonthica have been completed in TZE-Y Pop STR C0. In order to determine whether or not to continue with the recurrent scheme, it was desirable to evaluate the amount of residual genetic variance and as...
Maize (Zea mays L.) production in west Africa (WA) is constrained by drought, Striga hermonthica infestation and low soil nitrogen (N). Maize varieties resistant to Striga, drought, and low N are ideal for WA, but genotype × environment interaction on these traits are usually significant due to d...
Two maize (Zea mays L.) populations, TZE-W Pop DT STR C4 (Reg. No. GP-574, PI 654407), white- grained, fl int/dent, and TZE-Y Pop DT STR C4 (Reg. No. GP-575, PI 654408), yellow-grained, fl int/dent with drought tolerance and moderate levels of resistance to the fl owering parasitic witchweed, Str...
Striga hermonthica (Del.) Benth.is a majorbiotic constraint to increased maize (Zea mays L.) productionand productivity in West and Central Africa (WCA).Twenty-three early maize inbreds were evaluated underartificial Striga infestation and Striga-free conditions at 2locations for 2 years in Niger...
Maize (Zea mays L.) cultivars combining high grain yield with elevated levels of lysine, tryptophan, and desirable endosperm modification, could reduce food insecurity and malnutrition in West and Central Africa (WCA). Sixteen early- and nine extra-early-maturing quality protein maize (QPM) and n...
Striga and drought are major constraints to maize (Zea mays L.) production in the savannas of west and central Africa (WCA). A study was conducted in 2005 and 2006 in Nigeria to determine the level of resistance to Striga hermonthica for two early-maturing maize populations, one white and one yel...
