Molecular breeding for enhancing iron and zinc content in wheat grains.

Abstract This chapter provides information on the importance of biofortification as a cheap, sustainable and environmentally friendly approach to increase micronutrient contents in plants. The merging of breeding approaches with genetic engineering techniques, such as quantitative trait locus analysis, marker-assisted breeding, gene cloning and gene transformation from wild wheat relatives, in order to develop micronutrient-rich wheat cultivars is also highlighted.
