“…China has the largest wheat production and consumption suffering from severe FHB damages, especially in the Middle and Lower Reaches of the Yangtze River with its warm, humid environment. In recent years, FHB has become more serious and expanded in the major wheat production area of the Yellow and Huai River Valleys [4].…”

“…In addition, Fhb1 has shown linkage with poor agronomic traits and single resistance gene has been proven to be a major limitation for FHB resistance breeding as it may not provide sufficient protection under severe FHB epidemics [15,22,23]. Pyramiding Fhb1 and other major FHB resistance QTL into elite cultivars using MAS could be crucial for breeding new wheat varieties with better resistance to FHB [4,24]. Several cultivars such as Yang-mai158, Yangmai11 Yangmai12, Yangmai16, and Yangmai23 in the Middle and Lower Yangtze River Valleys with moderate resistance to FHB have been approved to be released and become main cultivars [25].…”

Background: Fusarium head blight (FHB), primarily caused by Fusarium graminearum, is a major threat to wheat production and food security worldwide. Breeding stably and durably resistant cultivars is the most effective approach for managing and controlling the disease. The success of FHB resistance breeding relies on identification of an effective resistant germplasm. We conducted a genome-wide association study (GWAS) using the highdensity wheat 90 K single nucleotide polymorphism (SNP) assays to better understand the genetic basis of FHB resistance in natural population and identify associated molecular markers.Results: The resistance to FHB fungal spread along the rachis (Type II resistance) was evaluated on 171 wheat cultivars in the 2016-2017 (abbr. as 2017) and 2017-2018 (abbr. as 2018) growing seasons. Using Illumina Infinum iSelect 90 K SNP genotyping data, a genome-wide association study (GWAS) identified 26 loci (88 marker-trait associations), which explained 6.65-14.18% of the phenotypic variances. The associated loci distributed across all chromosomes except 2D, 6A, 6D and 7D, with those on chromosomes 1B, 4A, 5D and 7A being detected in both years. New loci for Type II resistance were found on syntenic genomic regions of chromsome 4AL (QFhb-4AL, 621.85-622.24 Mb) and chromosome 5DL (QFhb-5DL, 546.09-547.27 Mb) which showed high collinearity in gene content and order. SNP markers wsnp_JD_c4438_5568170 and wsnp_CAP11_c209_198467 of 5D, reported previously linked to a soil-borne wheat mosaic virus (SBWMV) resistance gene, were also associated with FHB resistance in this study. Conclusion: The syntenic FHB resistant loci and associated SNP markers identified in this study are valuable for FHB resistance breeding via marker-assisted selection.
