Fig. 1. Schematic depiction of the maize chromosomes, with horizontal lines demarking bins (Davis et al., 1999). Centromeres are shown as thick black lines. Ovals represent QTLs mapped in GEFR population and rectangles represent QTLs mapped in the NCB population on the basis of means across all testing environments. Hash marks indicate QTL for both Fusarium ear rot and fumonisin contamination, black shapes indicate QTL for fumonisin contamination only, and white shapes indicate QTL for Fusarium ear rot only. Genetic maps and QTL locations for individual populations are presented in Supplemental Fig. 1 and 2.
