A study was conducted to evaluate the use of different intra-row spacing to optimize Striga infesta- tion for resistance screening in maize. Five maize geno- types of different genetics backgrounds and contrasting reactions to Striga hermonthica were evaluated under four intra-row spacing. The ex...

The effects of nitrogen (N) rate and weed interference on the grain yield of four corn genotypes were investigated in 2002 and 2003 at Ikenne (7u389N, 3u429E), Shika (11u119N, 7u389E), and Samaru (10u249N, 7u429E) in Nigeria. Nitrogen (N) at 0, 30, 60, and 90 kg N ha21 were the main plot treatmen...

Striga-resistant maize inbred lines are of interest to maize breeding programs in the savannas of Africa where the parasitic weed is endemic and causes severe yield losses in tropical maize. Assessment of the genetic diversity of such inbred lines is useful for their systematic and efficient use ...

Low soil nitrogen (low N) limits maize (Zea maysL.) production in sub-Saharan Africa (SSA). Knowledge of inheritance of tolerance to low N in inbred lines selected for drought tolerance would be useful for developing hybrids adapted to low N conditions. The objectives of this study were to determ...

Maize is an important food crop in the Guinea savannas of Nigeria where it is gradually replacing the traditional cereal crops, such as sorghum and millet because of its high productivity. Despite its high yield potential, maize production is faced with numerous constraints. One of these Is droug...

In the dry savannas of West and Central Africa, where low soil fertility, unpredictable rainfall, weed competition and recurrent drought are major constraints to maize production, the development of tropical maize genotypes with high and stable yields under drought and low-nitrogen condition is v...

• Breeding for resistance to Striga in maize (Zea mays), with paucity of donor source and known mechanisms of resistance, has been challenging. • Here, post-attachment development of S. hermonthica was monitored on two maize inbreds selected for field resistance and susceptibility reactions to St...

Maize (Zea mays L.) production in west and central Africa (WCA) is constrained by the parasitic weed Striga hermonthica (Del.) Benth and recurrent drought. Two early maize populations, TZE-W Pop DT STR C0 (white) and TZE-Y Pop DT STR C0 (yellow), developed from diverse genetic backgrounds, were s...

Increasing the concentrations of Fe and Zn in staple food crops through breeding has been proposed as one strategy to minimize the adverse effects of widespread mineral deficiencies in humans. This approach requires the presence of adequate genetic differences in concentrations of grain minerals ...
