摘　　要：对小麦茎基腐病(FCR)抗性位点研究进行综述。目前,在小麦所有的21条染色体上定位了140个抗性QTL,含10个抗性基因,虽然报道的抗性位点很多,但主效位点不明确,严重影响小麦FCR抗性改良进程。分析了小麦FCR抗性位点研究中的主要问题,提出了统一抗性鉴定标准、增强成株期抗性研究等建议,以明确抗FCR主效位点/基因并开发分子标记,通过分子标记辅助选择促进FCR抗性改良进程。This article reviewed the resistance loci for Fusarium crown rot(FCR)in wheat.Currently,140 loci for FCR resistance have been identified locating on all 21 wheat chromosomes,including 10 resistance genes.Although there are many loci for FCR resistance reported,the effect of major loci is not clear,which seriously impacts the process of improving wheat FCR resistance.The main problems in the study of FCR resistance sites in wheat were analyzed;Suggestions on the unified identification method of FCR and strengthening the identification of adult resistance were put forward.It is crucial for identifying the main loci/genes for FCR resistance and developing the molecular markers,which will promote the breeding process of FCR resistant wheat cultivars through molecular marker assisted selection.
