Research Advances in Wheat Breeding and Genetics for Fusarium Head Blight Resistance

Fusarium head blight (FHB) is a severe disease of wheat, mainly caused by Fusarium graminearum, which greatly reduces wheatproduction and directly affects human and animal health due to the mycotoxins produced in wheat grains. To develop high-quality, stableyields, and mycotoxin-free crop, it is essential to first understand the genetic basis of wheat FHB-resistance, and to design molecular markersfacilitating the selection of FHB-resistant varieties. However, despite extensive global research efforts, genetic research and marker developmentfor the selection of FHB-resistant varieties, in Korea, are insufficient. Here, we summarize recent studies on FHB-resistance genes, resistanceresources, quantitative trait locus analysis, and genome-wide association studies to enhance our understanding of FHB and the breeding ofFHB-resistant domestic wheat cultivars.
