Aspergillus flavus infection of maize and subsequent contamination with carcinogenic aflatoxins poses serious health concerns, especially in developing countries. Maize lines resistant to A. flavus infection have been identified; however, the development of commercially-useful aflatoxin-resistant...

This study measured the impacts of drought tolerant maize varieties (DTMVs) on productivity, welfare, and risk exposure using household and plot-level data from rural Nigeria. The study employed an endogenous switching regression approach to control for both observed and unobserved sources of het...

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...

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...

Introduction of exotic maize (Zea mays L.) into adapted tropical germplasm may enhance genetic variability and lead to greater progress from selection. The first objective of this study was to determine if yellow endosperm lines derived from adapted x exotic backcrosses contain exotic alleles tha...

Maize (Zea mays L.) production in west Africa (WA) is constrained by drought, Striga hermonthica infestation and low soil nitrogen (N). Maize varieties resistant to Striga, drought, and low N are ideal for WA, but genotype × environment interaction on these traits are usually significant due to d...

Maize (Zea mays) is a staple food crop in sub-Saharan Africa, but itsproduction is threatened byStriga hermonthica(Del.) Benth. Transferof resistance genes from wild relatives may increase resistance toS. hermonthicain tropical maize. The objective of this study was todetermine the combining abil...
