Genetic Characterization of a Wheat Association Mapping Panel Relevant to Brazilian Breeding Using a High-Density Single Nucleotide Polymorphism Array

Abstract: Bread wheat (Triticum aestivum L.) is one of the world’s most important crops. Maintaining wheat yield gains across all of its major production areas is a key target toward underpinning global food security. Brazil is a major wheat producer in South America, generating grain yields of around 6.8 million tons per year. Here, we establish and genotype a wheat association mapping resource relevant to contemporary Brazilian wheat breeding programs. The panel of 558 wheat accessio… Show more

“…The major FHB resistance gene Fhb2 has been mapped to the short arm of 6B between the markers gwm644 and gwm133, with reduced FDK and FHB severity being derived from the cultivar Sumai 3 [81]. FDK has been previously mapped on the short arm of chromosome 6B within the Fhb2 region in Brazilian germplasm, using bi-parental mapping with the cultivar Frontana [23] and through genome wide association mapping using a panel of wheat breeding lines and varieties relevant to Brazilian wheat breeding [18]. The QME.Tgw.jic-6B interval sits within 10.18 Mb of Kukri_c25377_240, the closest significant marker associated with FDK in the study by Mellers et al [18], and is 53.57 Mb outside the Fhb2 fine mapped region [81,82].…”

“…The Brazilian spring wheat panel included entries released between 1922 to 2013. Year of varietal release and trait data were obtained from (39). The UK wheat panel consists of winter wheat varieties that were either registered or in use from 1916 to 2010.…”
