Due to soil changes, high density planting, and the use of straw-returning methods, wheat common root rot (spot blotch), Fusarium crown rot (FCR), and sharp eyespot (sheath blight) have become severe threats to global wheat production. Only a few wheat genotypes show moderate resistance to these root and crown rot fungal diseases, and the genetic determinants of wheat resistance to these devastating diseases are poorly understood. This review summarizes recent results of genetic studies of wheat resistance to common root rot, Fusarium crown rot, and sharp eyespot. Wheat germplasm with relatively higher resistance are highlighted and genetic loci controlling the resistance to each disease are summarized.

小麦对普通根腐病(斑点斑),镰刀菌冠腐病和尖锐眼斑的抗性遗传

由于土壤变化,高密度种植以及使用秸秆还田方法,小麦普通根腐病(斑斑病),镰刀菌冠腐病(FCR)和尖锐的眼斑病(鞘枯病)已成为全球小麦生产的严重威胁。仅有少数小麦基因型显示出对这些根腐病和冠腐病的中等抗性,而小麦对这些毁灭性疾病的抗性的遗传决定因素却知之甚少。这篇综述总结了小麦对普通根腐病,镰刀菌冠腐病和尖锐斑点的抗性的遗传研究的最新结果。突出了具有相对较高抗性的小麦种质,并总结了控制每种疾病抗性的遗传基因座。
