Iron (Fe) and Zinc (Zn) concentrations in tuberous roots of twenty-five cassava (Manihot esculenta Crantz) genotypes were determined over 2 years (2004/2005 and 2005/2006) at five locations representing distinct agroecologies in Nigeria. The objectives were to study the magnitude and nature of ge...

Cassava contains little zinc, iron, and β-carotene, yet it is the primary staple crop of over 250 million Africans. This study used a 24-hour dietary recall to test the hypothesis that among healthy children aged 2–5 years in Nigeria and Kenya, cassava’s contribution to the childrens’ daily diets...

Twenty elite early-maturing (75−90 days) tropical maize varieties grown in three diverse agroecologies in West Africa were evaluated to identify varieties with high kernel-Fe and -Zn and bioavailable Fe levels. Bioavailable iron was assessed using an in vitro digestion/Caco-2 cell model. Signific...

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...

Though cassava (Manihot esculenta Crantz) is a staple for many poor people in Africa, it has major nutritional disadvantages. The tuberous root has very low levels of essential nutrients. Consequently, malnutrition is widespread among the people who depend on as a staple in their diet. Breeding c...
