The genetic versus physical locations (a), and false discovery rate (FDR) adjusted P value and pair-wise linkage disequilibrium (LD) squared allele frequency correlation (r²) (b) of Single Nucleotide Polymorphisms (SNPs) on chromosome 5A that were associated with Fusarium head blight traits (severity and index) of DT696 derivatives at the Brandon (BD) environment. Chromosomal map position of markers on the consensus genetic map (GM) of Maccaferri et al.²⁴ and the corresponding physical distance on durum wheat cv. Svevo³⁸ and wild emmer wheat accession Zavitan³⁹ reference physical maps (PM) are compared (a). The genome-wide association study (GWAS) FDR adjusted P value of each SNP significantly associated with FHB traits are projected over its LD r² values (b). The vertical red line shows the position of the major vernalisation gene VRN1 (TraesCS5A01G391700) and the areas shaded in red are the locations of the 5A2–1 and 5A2–2 intervals that had lower FDR adjusted P value than the surrounding markers for FHB index at Brandon in 2016. The order of SNPs in panel (b) is inferred from their position on cv. Svevo physical map.
