LD heat plots of ten candidate genes. Analysed sequences, including the promoter and complete coding sequences of ScCbf6 and ScCbf9b, and partial coding sequences of ScCbf12, ScCbf14, and ScCbf15; ScVrn1 was not included due to a lack of pairwise comparisons, since only one Indel was observed. Exons, and 5'- or 3'-flanking regions are represented by grey cylinders and black lines, respectively. White cylinders with dashed lines indicate non-amplified exons. Black triangles represent polymorphic sites starting from "SNP1" on the top of each graph. Each grid represents the strength of LD estimated by r2 for each pairwise comparison between polymorphic sites with a minor allele frequency (MAF) > 0.05. The colour legend for r2values is given on the right side.
