aTag-SNP is the SNP with the strongest association in the defined QTL region. bChromosome of the identified locus is based on the tetraploid wheat consensus map generated by Maccaferri et al. (2015a). cConfidence interval of the identified locus derived from a genetic distance of ±2.25 cM from the tag-SNPs; confidence interval positions based on the tetraploid wheat consensus map generated by Maccaferri et al. (2015a). dResistance allele of the tag-SNP is highlighted in bold and underlined. eResistance allele frequency of the tag-SNP. fPhenotypic variances explained by the identified locus calculated in MLM with Q3 and K. gSignificant (P < 0.005) SNPs associated with the corresponding Pst races and fall into a genetic distance of 2.25 cM from the tag-SNPs. NA means not applicable. h-log (Marker-trait association P values); “-” means not significant; -log (P) > 2.3 and > 3 correspond to P-values < 0.005 and < 0.001.
