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...

Twelve samples of Striga hermonthica seed were collected from four host crops [millet (4), sorghum (4), a sorghum/millet intercrop (3) and maize (1)] from all the main areas of S. hermonthica infestation in Nigeria and were tested on eight genotypes of three test crops [maize (4), sorghum (2) and...

Tzi (tropical Zea inbred) lines 1, 3, 4, 8 to 13, 15, 17, 18, 24, 25, 27, 28 and 30 are currently at the S6 stage of inbreeding; they have been selected for resistance to maize streak virus (MSV) throughout the inbreeding process using artificial field infestation with viruliferous leafhoppers. M...

Two sets (white- and yellow-kernelled) of six cultivars of field-maize, each comprising three hybrids and three open-pollinated (OP) varieties, were evaluated for green-maize productivity under three levels of nitrogen fertilisation (0, 60 and 120  kg  ha−1) at two locations in southwestern Niger...

phytoparasite, Striga hermonthica (Del.) Benth., infests millions of hectares of cultivated fields of cereal crops in sub-Saharan Africa. Yield losses are often 70 but can be as high as 100% and farmers often abandon infested fields and move to new areas. The objectives of this study were to inve...

The parasltie flowering plants, Striga species, represent the largest biological constraint to cereal and legume crop production in sub-Saharan Africa. Eighty-three percent of Striga worldwide (35 species) occurs in Africa. Among them, Striga hermonthica causes the greatest damage. The IITA's sci...

A parasitic plant, Striga hermonthica (Del.) Benth., infests millions of hectares of arable land in sub-Saharan Africa, and it threatens production of major cereal crops including maize (Zea mays L.). Erratic natural infestation is considered a major constraint to assess host plant resistance to ...

Maize is the most important cereal in sub-Saharan Africa. It is relatively inexpensive and provides many families with much-needed nutrients. For the farmers, it matures early and Is a source of ready income. Maize production Is being threatened by some diseases and pests, among which are downy m...

Biotic constraints (insects, diseases, parasitic weeds) and abiotic stresses (drought) are widespread and pose a constant threat to maize production worldwide. Tropical environments provide the greatest opportunity for evolution of insects and diseases because of the favourable year- round climat...
