Yields of maize (Zea mays L.) are remarkably low in sub-Saharan Africa and yet farmers have limited access to improved varieties. The objective of this study was to determine combining ability and heterosis of 18 elite maize inbred lines in environments prone to northern corn leaf blight (NCLB) disease in the mid-altitude tropics. Nine elite inbred lines(More)
PURPOSE Vitamin A deficiency is among major health problems worldwide that leads to blindness, retarded growth and death, particularly in developing countries. In these countries, vitamin A deficiency largely affects pre-school children, pregnant and lactating mothers, and the rural poor. For instance, the predicted prevalence of vitamin A deficiency for 36(More)
Conversion of normal maize (Zea mays L.) into quality protein maize (QPM) significantly improves its nutritional value for humans and animals. Highland adapted normal maize inbred lines were backcrossed with selected QPM donor lines to incorporate the opaque-2 gene. The objectives of this study were to verify the genetic purity, determine the effect of(More)
Bread wheat genotypes with slow rusting stem rust resistance were crossed in a half-diallel mating design to identify superior parents for stem rust resistance combined with high grain yield (GY) and related traits. Significant mid-parent heterosis for area under disease progress (AUDPC) was observed in crosses 7041-1 × Danda’a and Danda’a × Kubsa. H04-2 ×(More)
