To identify loci associated with Fusarium head blight resistance in common wheat using synthetic hexaploid wheat.
Evaluated recombinant inbred lines derived from synthetic hexaploid wheat and a resistant wheat variety across four environments.
Genotyped lines using wheat 50K single-nucleotide polymorphism array.
Developed and validated KASP markers for identified loci in common wheat accessions.
Identified QFhb.haas-2DL, QFhb.haas-3BS, and QFhb.haas-3BL associated with FHB resistance, explaining up to 10.4% of phenotypic variance.
Overlaps noted with known resistance loci, suggesting novel sources of resistance for breeding.
Validated KASP markers for practical application in breeding programs.
