Deficiencies of vitamin A, iron, and zinc are widespread in sub-Saharan Africa, where the diets are mainly plant-based and the intakes of animal products are low. The overall objective of this investigation was to determine the extent of genetic variation of these micronutrients in 16 yellow-seed...

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...

Registration of 26 tropical maize germplasm lines with resistance to Striga hermonthica
Two tropical maize composites were subjected to four cycles of reciprocal recurrent selection to develop divergent inbred lines with good combining ability. This study was conducted to examine the extent of genetic diversity, changes in allele composition and genetic structure, of 100 randomly se...

Genetic divergence in two tropical maize composites after four cycles of reciprocal recurrent selection
Until recently, breeding programs in Africa placed little emphasis on grain quality improvement. Consequently, some farmers have not adopted improved high yielding varieties because they lacked desired quality characteristics for processing and other end uses. We conducted this study to determine...
