Striga-resistant maize inbred lines are of interest to maize breeding programs in the savannas of Africa where the parasitic weed is endemic and causes severe yield losses in tropical maize. Assessment of the genetic diversity of such inbred lines is useful for their systematic and efficient use ...
Hybrid maize seed was the first commercially available F1 seed. Inbred lines serve as parents for commercial production of single-cross hybrid seed. Cooperation between seed companies, research institutes, and government institutions is essential to the successful development of productive hybrid...

Maize is one of the important food crops worldwide. It has a remarkable productive potential. However, considerable variation exists among varieties in morphology and growth habit. Management of a maize crop with respect to interaction of genotype and environment requires specific knowledge of ma...
Striga hermonthica, an obligate root parasite of grasses, is one of the most severe constraints to cereal production in sub-Saharan Africa. In the recent past, prior to increased production pressure on land, S. hermonthica was controlled in African farming systems by prolonged crop rotations with...

The pink stem borer (Sesamia calamistis Walker (Pyralidae)) and the sugarcane borer (Eldana saccharina Hampson (Noctuidae)) are among the most damaging pests of maize in West and Central Africa, a region where IITA invests considerable effort in improving productivity of maize-based systems. The ...

Poor soil fertility and recurrent drought are major constriants to maize production in the West Africa savanna. The development of maize cultivars with superior rooting system to absorb nitrogen and water efficiently from the soil is desirable. However, direct measurement of root characteristics ...

Thirty-six inbred lines selected in West and Central Africa for moderate to high resistance to maize ear rot under conditions of severe natural infection were screened for resistance to aflatoxin contamination using the previously established kernel screening assay. Results showed that more than ...

Maize is a major cereal crop. Worldwide, wheat, maize, and rice are produced in greater quantities than any other crop. Of these crops, maize has the highest average yield per hectare. Maize is a good source of energy for both humans and animals. It is high-yielding, easy to process and readily d...
