Biofortification by enhanced mineral density in maize grain through genetic improvement is one of the efficient ways to solve global mineral malnutrition,in which one key step is to detect the corresponding Quantitative Trait Loci (QTL).In this work,a maize recombinant inbred population (RIL) was grown to maturity in four field environments with two locations (!A) two years.Phenotypic data of mineral nutrition concentration,content and yield were determined for grain copper (Cu),iron (Fe),manganese (Mn),zinc (Zn),magnesium (Mg),potassium (K) and phosphorus (P).Analysis of variance (ANOVA) showed significant effects of genotype,location and year for all investigated traits.Location showed the highest effect for all mineral yields,and Zn and Cu content and concentration,while year had the strongest impact for Mn,K,and P content and concentration.
