Abstract

Micronutrient deficiency in food crops affects one-half of world people especially in developing countries. In many micronutrient-deficient regions, cereal grains as the dominant staple food are naturally low in minerals, vitamins and protein, increasing a risk of hidden hunger. Biofortification of cereals is a new approach to control micronutrient deficiencies and vitamin A in developing countries. Predictive cost-benefit evaluates have proven that biofortification is important in controlling of malnutrition. Biofortification is the development of micronutrient-dense food crops using conventional breeding and/or biotechnology practices. Biofortified crop system is highly sustainable over years, cost- effective, target low-income households, and available in remote rural areas. Micronutrient enrichment traits are present in the genome of cereals that could permit substantial improvement in grain zinc, iron and carotenoids without negatively impressing grain yield. The genetically fortifications traits are stable across various climatic environments and soil types. Biotechnology tools in genomic, molecular biology, identifying nutrient absorption enhancers and inhibitors genes can provide better and more efficient complementary breeding tools. A significant development in the next few years will be the use of molecular markers associated with accumulation of Zn and Fe in cereals. The identification of major-effect molecular markers can speed up the development of high yielding biofortified cereals even in micronutrient-deficient soils. DNA markers allow screening for micronutrient-rich crops independently of the environmental variability or growth stage. If markers are close enough to a gene of interest, they can be directly used in marker-assisted selection (MAS).
