Fig. 1. MNBrite pedigree. A Chevron-derived progeny, CI9539, was the parent in the first cycle of breeding. M44 has the pedigree Nordic/Manker/3/Morex//Manker/63AB2987-32.

Fig. 2. Revised genetic linkage map of the Chevron x M69 (CM) mapping population originally published in de la Peña et al. (1999). The bars are adjacent to the marker interval on the map in which the QTL was detected. QTL for kernel discoloration (KD) and grain protein concentration (GPC) are shown for individual environments and are coded to identify the environments in which they were detected (Cr95 = Crookston 1995; Mo95 = Morris 1995; Sp95 = St. Paul 1995; Sp97 = St. Paul 1997). See Tables 2 and 4 for parameter estimates for the QTLs identified for KD and GPC, respectively.

Fig. 3. Quantitative trait loci associated with kernel discoloration (KD) and grain protein concentration (GPC) on chromosome 6(6H) for Chevron/M69 (CM) and MNBrite/M96 (MM) mapping populations. QTL for KD and GPC are shown for individual environments and are coded to identify the environments in which they were detected. Cr95 = Crookston 1995; Sp95 = St. Paul 1995; Mo95 = Morris 1995; Sp97 = St. Paul 1997; Cr97 = Crookston 1997; SpKD97 = St. Paul B. sorokiniana nursery 1997; Cr98 = Crookston 1998; Sp98 = St. Paul 1998; SpKD98 = St. Paul B. sorokiniana nursery 1998). See Tables 5 and 6 for parameter estimates for the QTLs identified for KD and GPC.
