Chromosomal regions identified by genome-wide association for 11 quality traits measured in 132 maize inbred lines. Horizontal bars represent each of the 10 maize chromosomes. Genomic regions labelled accordingly to the trait, followed by a number identifying each individual region; vertical lines below correspond to the location of the genomic region associated with the trait variation in megabase pairs using the B73 reference genome (Zea mays B73 RefGen_v3). Co-localized regions associated with multiple traits are highlighted in blue. Quality traits: PR – percentage of protein; FI – percentage of fiber; FT – percentage of fat; STL – percentage of starch in lyophilized flour; SIZEL – mean particle size in lyophilized flour; PV – peak (maximum) viscosity; TV – trough (minimum) viscosity; FV – final viscosity; BD_SqRt – squared-root transformed values of the breakdown viscosity; SB1 – setback from trough viscosity; SB2 – setback from peak viscosity
