Formation of heterotic groups and understanding genetic effects in a provitamin a biofortified maize breeding program
Developing biofortified maize cultivars is a viable approach to combat the widespread problem of vitamin A deficiency among people for whom maize is a staple food. To enhance CIMMYT's provitamin A maize breeding efforts, ...
Genome‑wide association analysis reveals new targets for carotenoid biofortification in maize
Key message Genome-wide association analysis in CIMMYT’s association panel revealed new favorable native genomic variations in/nearby important genes such as hydroxylases and CCD1 that have potential for carotenoid b ...
Genetic architecture controlling variation in grain carotenoid composition and concentrations in two maize populations
The genetic basis for the variation in maize grain carotenoid concentrations was investigated in two F2:3 populations, DEexp × CI7 and A619 × SC55, derived from high total carotenoid and high -carotene inbred lines. A ...
Cell wall composition and biomass digestibility diversity in Mexican maize (Zea mays L) landraces and CIMMYT inbred lines
Maize is one of the most important crops worldwide. Historically, breeding efforts in this crop have been primarily focused on the improvement of grain yield and stability and just recently also on the potential utility ...
Addressing climate change effects and meeting maize demand for Asia
This includes the extended summaries of the scientific presentations made during the 11th Asian Maize Conference held in Nanning, China, during 7-11 November 2011. The Conference is co-organized by the International Maize ...
The usefulness of iron bioavailability as a target trait for breeding maize (Zea mays L.) with enhanced nutritional value
Iron (Fe) deficiency is the most widespread nutritional problem, affecting as many as half of the world's population. Only a small fraction (2?15%) of Fe from plant sources is typically bioavailable, that is, available for ...
Physical properties and carotenoid content of maize kernels and its nixtamalized snacks
Vitamin A and protein deficiencies afflict hundreds of millions of people, and because maize is a staple food providing a large portion of energy and nutrients for many, its genetic fortification or biofortification could ...
Provitamin A carotenoid bioavailability: what really matters?
Micronutrient malnutrition, or "hidden hunger," affl icts a large part of the world's population, with vitamin A defi ciency among the most prevalent public health problems. Provitamin A carotenoids in plant foods are a ...
Enhancing the mineral and vitamin content of wheat and maize through plant breeding
More than half of the world's population suffers micronutrient undernourishment. The main sources of vitamins and minerals (iron, zinc, and vitamin A) for low-income rural and urban populations are staple foods of plant ...
Reliable and inexpensive colorimetric method for determining protein-bound tryptophan in maize kernels
Biofortification programs in maize have led to the development of quality protein maize (QPM) with increased contents of the essential amino acids lysine and tryptophan, and increased nutritional value for protein deficient ...
