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.
