QTL mapping for grain zinc and iron concentrations and zinc efficiency in a tetraploid and hexaploid wheat mapping populations

Zinc and iron deficiencies are the most important forms of malnutrition globally, and caused mainly by low dietary intake

Abstract

Zinc (Zn) and iron (Fe) deficiencies are the most important forms of malnutrition globally, and caused mainly by low dietary intake. Wheat, a major staple food crop, is inherently low in these micronutrients. Identifying new quantitative trait loci (QTLs) for high grain Zn (GZn) and Fe (GFe) will contribute to improved micronutrient density in wheat grain. Using 2 recently developed recombinant inbred line (RIL) mapping populations derived from a wild progenitor of a tetraploid population 鈥淪aricanak98聽脳聽MM5/4鈥 and an hexaploid population 鈥淎dana99聽脳聽70,711鈥, multi-locational field experiments were conducted over 2聽years to identify genomic regions associated with high grain Zn (GZn) and grain Fe (GFe) concentrations.
