Exhibition of QTL positions on chromosome. Linkage groups are colored and represented according to the marker density. The colors represent a density scale of markers ranging from red (high-density regions) to blue (low-density regions), and the marker position is exhibited by a black line. Ten QTLs for seed Fe and Zn content identified in the GB RIL population are shown on the right side of the corresponding linkage group. Red, purple, green, and orange represent the 18GZ, 18ZC, 19GZ, and 19ZC environments, respectively. Cyan represents the QTLs using QEI mapping analysis
