Fig. 3From: Genome-wide association analysis on pre-harvest sprouting resistance and grain color in U.S. winter wheatDistribution of grain color (GC) scores in the association mapping population predicted by Tamyb10 gene markers. Six allele combinations of three GC genes on chromosomes A, B and D separated 185 accessions into eight genotypes. Lower case represents a white grain allele and upper case represents a red grain allele in each locus. The three letters in each genotype represent three gene loci in the chromosomes A, B and D, respectively, e.g, Abc indicates red allele on 3A and white alleles on 3B and 3D. GC scores used a 1-4 scale with 1 for white grain and 4 for red grainBack to article page
