BnaC07g30920D is associated with SOC reduction in rapeseed. a Local Manhattan plot showing the SNPs at the peak region (indicated by the dotted red line) on Chr.C07 that are significantly (−log₁₀p > 5) associated with SOC. The small black triangle indicates the SNP, ChrC07_35249208, associated with BnaC07g30920D. b Haploblock showing markers in linkage disequilibrium (LD). The black dot on the LD heat map indicates the position of the representative SNP, ChrC07_35249208. The linkage degrees between each of the two positions and between the SNPs and the candidate gene BnaC07g30920D are shown by the color keys indicating r² values. c A sketch magnifying the relative distance between the significant SNP associated with SOC and BnaC07g30920D
