The quest for precise and rapid phenotyping of germplasm is increasing the interest of breeders and physiologists in the application of remote sensing techniques in maize breeding. Twenty-four drought-tolerant maize inbred lines were crossed using a modified North Carolina II mating scheme to gen...

The study aimed at examining the associations between yield and other traits under drought stress and non-stress conditions. A total of 150 MARS testcrosses were evaluated under both conditions at the International Institute of Tropical Agriculture substation for two years under during the dry se...

Vitamin A Deficiency (VAD) is a major public health problem in Sub-Saharan Africa affecting 33 million preschool-age children. Enrichment of maize varieties with provitamin A could provide sustainable and affordable solution to VAD. This study was conducted to understand the extent of GEI effects...

In the dry savanna of West and Central Africa, where unpredictable rainfall and recurrent drought are major constraints to maize production, the development of tropical maize genotypes with high and sable yields under drought is very important since access to drought-tolerant genotypes may be the...

Assessment of the stability of micronutrients is important in breeding for the enhanced nutritional quality of staple food crops as a means to alleviate malnutrition. Twenty early-maturing elite tropical maize (Zea mays L.) genotypes were evaluated over 2 years at three locations representing thr...


Oikeh, S.O.Menkir, A.Maziya-Dixon, B.B.Welch, R.M.Glahn, Raymond P.Gauch, G.[Environmental stability of iron and zinc concentrations in grain of elite earlymaturing tropical maize genotypes grown under field conditions]Environmental stability of iron and zinc concentrations in grain of elite earlymaturing tropical maize genotypes grown under field conditions
