Secondary traits can improve precision with which drought or low soil nitrogen (low-N) tolerant maize (Zea mays L.) genotypes are identified, compared to measuring only grain yield under each stress. The objective of this study was to identify secondary traits for indirect selection for yield imp...

Maize improvement at the International Institute of Tropical Agriculture (IITA), which began in the 1970s, built on the germplasm and experience of earlier years. The main breeding emphasis was to develop maize cultivars and hybrids with high yield potential and durable resistance to diseases and...

Drought occurrence and striga hermonthica (Del.) Benth infestation are formidable maize (Zea mays L.) production constriants in the savanna zones of West and Central Africa (WCA). The West and Central Africa collaborative Maize Research Network (WECAMAN), in collaboration with the International I...

The Maize streak virus (MSV) disease has been one of the most devastating diseases of maize (Zea mays L.) in all the countries of West and Central Africa (WCA). For a long time, breeding for resistance to the disease was frustrating because of lack of facilities for uniform artifi cial inoculatio...

Maize (Zea mays) is an important crop for food, feed, and agroindustrial raw material produced primarily in the savannah but also in other agroecologies of West and Central Africa (WCA). Maize production in the savannah has been constrained by cultivation of inappropriate varieties, biotic and ab...

The major thrust of the West and Central Africa Collaborative Maize Research Network (WECAMAN) has been on the development of early and extra-early maize varieties and associated agronomic practices. Adoption of these varieties and, to some extent, the complementary agronomic practices by farmers...

Maize (Zea mays L.) is cultivated under a broad range of climatic conditions in West and Central Africa (WCA). Unfortunately, maize production is constrained by a host of abiotic and biotic stresses, including drought, low soil fertility, diseases, insect pests, and the parasitic weed Striga herm...

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...

Full-sib families derived from Pool 16 DT, a tropical maize ( Zea mays L.) population, were evaluated in the 1995/96 and 1997/98 dry seasons, using two sites each season in Côte d’Ivoire. In all sites, the crop was irrigated from planting to about 2 weeks before anthesis, irrigation was discontin...
