Ear-rot-causing fungi, including Aspergillus and Fusarium spp., are common in maize in West and Central Africa. These fungi contaminate maize with mycotoxins that pose serious potential health hazards to humans in these areas. A collaborative germplasm screening project was initiated between the ...

Breeding maize for resistance to mycotoxins at IITA
The International Institute of Agriculture (IITA) is among the major suppliers of genetic materials to national agricultural research and extension systems in West and Central Africa for the development of improved maize varieties. This paper presents the results of a survey of the impact of germ...

Impact of IITA germplasm improvement on maize production in West and Central Africa
Recurrent selection under artificial S. hermonthica infestation has significantly reduced the number of emerged Striga plants and increased grain yield under Striga infestation in broad-based populations. These populations have been sources of varieties and inbred lines with consistently high lev...

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...

Transgenic plant studies have lead to the breakthrough discovery of RNA silencing as a conserved mechanism for gene regulation across kingdoms. Recent molecular genetic studies have revealed a major role for RNA silencing in the formation of silent chromatin, characterized by histone modification...

Development of maize host resistance to aflatoxigenic fungi
The major mycotoxins studied at the Consultative Group on International Agricultural Re-search (CGIAR) institutes are aflatoxins in maize, groundnut, sorghum and cassava, Fusa-rium toxins in maize, wheat and sorghum, and ochratoxin in cocoa and cashew. Genetic en-hancement (both through plant bre...

Poor soil fertility and recurrent drought are major constriants to maize production in the West Africa savanna. The development of maize cultivars with superior rooting system to absorb nitrogen and water efficiently from the soil is desirable. However, direct measurement of root characteristics ...
