Abstract
Hunger and zinc (Zn) malnutrition are major health risk factors in the developingcountries. Wheat is a major staple food in the world but it is inherently low in grain Znconcentration especially when grown on Zn deficit calcareous soils. Therefore, producing Znenriched wheat grains at the farmers' fields is the best solution against human Zn deficiency.Biofortification approaches include selection, improvement and management of cultivated wheatgenotypes to ensure optimum grain Zn concentration for human consumption. Soil and foliarapplication of Zn to wheat grown on Zn deficient soils enhances both the grain yield and grain Znconcentration. Genotype screening for higher grain yield and grain Zn concentration isprerequisite to ensure adoptability of poor farmers to newly developed genotypes for Znbiofortification. Conclusively, simultaneous consideration of grain yield and grain Znconcentration of wheat is the sustainable and economical approach to achieve our food targets.
