Maize is a staple food crop for many people in Africa where millions of children, pregnant women and nursing mothers suffer from vitamin A deficiency. The β-carotene found in yellow maize can be used as a primary source of provitamin A. Several tropical yellow endosperm maize inbred lines with va...

Striga hermonthica is a major constraint to increased maize production and productivity in the savannas of West and Central Africa OVCA. The IITA-WECAMAN Maize Program has developed two extra-early source populations and several extra-early varieties, synthetics and inbred lines with resistance/t...

Drought stress causes significant yield reduction in maize Zea mays L. grown in sub-Saharan Africa (SSA. An understanding of the inheritance of drought tolerance would be useful in developing drought tolerant hybrids. The objectives of this study were to determine (i) the effects of the level of ...

Maize researchers in West and Central Africa (WCA) established the West and Central Africa Collaborative Maize Research Network (WECAMAN) in 1987 to tackle maize production constraints too formidable for individual national programs to overcome. The National Agricultural Research Systems (NARS) t...

Fusarium stalk rot is one of the most widespread and destructive diseases of maize, and deployment of resistant genotypes is one of the most effective strategies for controlling the disease. Fifty inbred lines and four checks from the breeding program of the International Institute of Tropical Ag...

Striga hermonthica (Del.) Benth is an obligate root parasite infecting maize (Zea mays L.) and causing considerable yield losses in Africa. Few studies have been conducted to determine the effectiveness of recurrent selection for improving resistance to S. hermonthica in maize. The objective of t...

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...

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...

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...
