Post-harvest losses in African maize in the face of increasing food shortage
Maize is the most important food staple for resource-poor smallholders in Africa, providing food and income to millions. One of the key constraints to improving food and nutritional security in Africa is the poor post-harvest ...
Bt-transgenic maize does not deter oviposition by two important African cereal stem borers, Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae)
Objective: To assess Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae) ovipositional responses on Bt (Event 216, containing the Cry1Ab gene) and isogenic non-Bt (CML ...
Past and potential impacts of maize research in Sub-Saharan Africa: A critical assessment
Over the past twenty years, research progress in maize, the single most important food staple in sub-Saharan Africa, has been comparable to progress in other primarily smallholder maize systems in the developing world, ...
Diallel analysis of grain yield and resistance to seven diseases of 12 African maize (Zea mays L.) inbred lines
Maize (Zea mays L.) is grown on 15 million ha in eastern and southern Africa. Several diseases are of common occurrence in the region and regularly result in significant yield losses. A collaborative regional disease nursery ...
Impediments to new improved maize variety testing and release in selected countries in Sub-Saharan Africa
Before farmers can benefit from new improved maize varieties with novel genetic information, new maize varieties have to undergo performance testing, registration and approval. The registration procedures require that new ...
Needs for and effectiveness of slow release herbicide seed treatment Striga control formulations for protection against early season crop phytotoxicity
Imidazolinone resistant maize seed dressed with imazapyr has been successfully used to control the parasitic weed Striga in many locations, and has begun to be commercially successful in Africa. Despite this, occasionally ...
Genetic diversity of African maize inbred lines revealed by SSR markers
(BioMed Central, 2007)
Knowledge of genetic diversity (GD) and relationships among maize inbred lines is indispensable in a breeding program. Our objectives were to (1) investigate the level of genetic diversity among maize inbred lines and (2) ...
