Genome-wide association of Single Nucleotide Polymorphisms (SNPs) with Fusarium head blight traits (severity [sev] and index [ind]) of the DT696 derivative field trials at Morden (MD) and Brandon (BD) locations in 2016 and 2017. Significant SNPs are shown as green dots and are determined based on Bonferroni adjusted P value which was equal to a marker-wise P value of 8.25 × 10−6. The y-axis represents the P value of the SNP–trait association on a − log10 scale and the x-axis represents the physical position of markers on 14 durum wheat chromosomes obtained from anchoring SNPs to the International Wheat Genome Sequencing Consortium (IWGSC) RefSeq v.1.0 genome assembly37. SNPs belonging to category UN are within scaffolds not assigned to the chromosomes in the IWGSC Refseq v1.0 assembly. Only environments and FHB traits with significant P values are presented as Manhattan plots, out of the GWAS results presented in Supplementary file 1.
