Advances in wheat breeding for resistance to Fusarium head blight

Fusarium head blight (FHB), mainly caused by graminearum, is one of the most devastating diseases wheat globally. FHB causes an extensive reduction in yield and reduces grain quality through its contamination with toxins such as deoxynivalenol (DON), T2 toxin, HT-2 nivalenol, zearalenone. This review provides overview updated progress genetic studies on resistance to FHB, emphasis sources gene/quantitative trait loci (QTL) mining, gene cloning, major genes/QTL identification molecular markers, mechanisms. The achievements breeding based phenotype selection markers was also summarised. Based systematic analysis limitations utilisation resistant materials, authors put forward three suggestions: First, toughen wheat, testing traits damaged kernel DON need special attention visual symptoms are less reliable, varieties should be popularised, screening genes strengthened; second use additive effect quantitative accumulated from existing reduce cost order create high yielding varieties. Thirdly, enhance research utilization new genes.
