Breeding and disseminating quality protein maize (QPM) for Africa
Quality protein maize (QPM) describes a range of maize cultivars with twice the content of limiting amino acids lysine and tryptophan compared with conventional maize, and has been developed to help reduce human malnutrition in areas where protein deficiency is prevalent and where maize is the major protein source in the diet, as in various parts of Sub-Saharan Africa (SSA). The International M...
متن کاملConsumer acceptance of quality protein maize (QPM) in East Africa.
BACKGROUND Undernutrition in sub-Saharan Africa remains problematic, and quality protein maize (QPM) can benefit populations whose diets are heavily based on maize and who are consequently at risk for inadequate intakes of quality protein. However, changes in the chemical composition of QPM may affect its sensory characteristics and, hence, acceptance. Acceptance tests were therefore conducted ...
متن کاملGenetic of resistance to ear rot causal agent (Fusarium moniliforme) in quality protein maize (QPM) using line×tester analysis
Breeding for QPM ear rot resistant cultivars could offer a reliable environmental and economic control of mycotoxins especially for the resource-poor communities that require inexpensive protein diets. This research aims at evaluating a testcross of QPM inbreds with ear rot resistant cultivars to develop resistant topcrosses with high grain protein quality and yield. Seven QPM inbreds (lines) a...

last rib backfat thickness, broken vertebrae, or scores for stomach ulcers (P > 0.21). Also, deletions of VTM premixes did not affect these same measurements (P > 0.22). However, RAC decreased (P < 0.01) backfat thickness by 8% and tended to decrease scores for stomach ulcers (P < 0.06). In conclusion, there were no interactions to suggest that the effects of RAC on growth performance and carca...
متن کاملQuality protein maize
Maize (Zea mays L.) plays a very important role in human and animal nutrition in a number of developed and developing countries, worldwide. Breeding for improved protein quality in maize began in the mid-1960s with the discovery of mutants, such as opaque-2, that produce enhanced levels of lysine and tryptophan, the two amino acids deficient in maize endosperm proteins. However, adverse pleiotr...
