“…FHB resistant cultivars typically exhibit more than one resistance type since each QTL/gene can produce several resistance reactions (Dweba et al, 2017). Although type II resistance has been widely studied as the primary resistance type and type V is almost a neglected class, studies on the sources of type III and type IV resistance are becoming of primary interest for most of the wheat breeding programs due to increased health concerns associated with harmful vomitoxins (Venske et al, 2019;Zhu et al, 2019).…”

“…Sumai 3 is a highly resistant spring wheat cultivar developed from a cross between resistant parents Funo and Taiwan Xiaomai and was released by the Suzhou Institute of Agricultural Sciences in 1970 (Cuthbert et al, 2006;Buerstmayr et al, 2009). Sumai 3 is the most widely used donor parent to deploy the major effect QTL Fhb1 in several wheat breeding programs throughout the world (Zhu et al, 2019). While Sumai 3 has been extensively used in North America, other regions are either relying on different sources of Fhb1 such as Shinchunaga in Japan and Norin 129 and Nigmai 9 in China or even dropping Fhb1 due to preferential selection for the stem rust gene Sr2 in International Maize and Wheat Improvement Center (CIMMYT) as both of these genes are linked in repulsion (Buerstmayr et al, 2019).…”

Among the biotic constraints to wheat (Triticum aestivum L.) production, fusarium head blight (FHB), caused by Fusarium graminearum, leaf rust (LR), caused by Puccinia triticina, and stripe rust (SR) caused by Puccinia striiformis are problematic fungal diseases worldwide. Each can significantly reduce grain yield while FHB causes additional food and feed safety concerns due to mycotoxin contamination of grain. Genetic resistance is the most effective and sustainable approach for managing wheat diseases. In the past 20 years, over 500 quantitative trait loci (QTLs) conferring small to moderate effects for the different FHB resistance types have been reported in wheat. Similarly, 79 Lr-genes and more than 200 QTLs and 82 Yr-genes and 140 QTLs have been reported for seedling and adult plant LR and SR resistance, respectively. Most QTLs conferring rust resistance are race-specific generally conforming to a classical gene-for-gene interaction while resistance to FHB exhibits complex polygenic inheritance with several genetic loci contributing to one resistance type. Identification and deployment of additional genes/ QTLs associated with FHB and rust resistance can expedite wheat breeding through marker-assisted and/or genomic selection to combine small-effect QTL in the gene pool. LR disease has been present in the southeast United States for decades while SR and FHB have become increasingly problematic in the past 20 years, with FHB arguably due to increased corn acreage in the region. Currently, QTLs on chromosome 1B from

“…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]. Most of Yangmaiseries cultivars don't carry the Fhb1 locus [26], indicating that other FHB resistance genes may be present in these cultivars and can be more easily applied to breeding.…”

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.
