The highest –log10 (p-value) of the markers from the QTL is given across all traits measured from the field trials performed in Brandon (BD), Morden (MD), and Indian Head (IH) in the years 2015, 2016 and 2017. –log10 (p) > 3 are in bold, values above the stringent Bonferroni significance threshold are underlined, and values below –log10 (p) = 1.3 are not shown. Physical position (Mb): physical location of SNP markers in the QTL from Chinese Spring assembly (International Wheat Genome Sequencing Consortium [IWGSC], 2018). Max R2: highest value for explained phenotypic variation for the marker across the traits and environments tested, expressed as%.
