Current information on barley resistance genes available from scientific papers and on-line databases is summarised. The recent literature contains information on 107 major resistance genes (R genes) against fungal pathogens (excluding powdery mildew), pathogenic viruses and aphids identified in Hordeum vulgare accessions. The highest number of resistance genes was identified against Puccinia hordei, Rhynchosporium secalis, and the viruses BaYMV and BaMMV, with 17, 14 and 13 genes respectively. There is still a lot of confusion regarding symbols for R genes against powdery mildew. Among the 23 loci described to date, two regions Mla and Mlo comprise approximately 31 and 25 alleles. Over 50 R genes have already been localised and over 30 mapped on 7 barley chromosomes. Four barley R genes have been cloned recently: Mlo, Rpg1, Mla1 and Mla6, and their structures (sequences) are available. The paper presents a catalogue of barley resistance gene symbols, their chromosomalocation and the list of available DNA markers useful in characterising cultivars and breeding accessions.
本文总结了从科学论文和在线数据库中获取的有关大麦抗性基因的现有信息。最近的文献包含了在大麦种质中鉴定出的107个针对真菌病原体（不包括白粉病）、致病病毒和蚜虫的主要抗性基因（R基因）的信息。针对大麦柄锈菌、大麦网斑病菌以及大麦黄花叶病毒和大麦温和花叶病毒鉴定出的抗性基因数量最多，分别为17个、14个和13个。关于白粉病抗性基因的符号仍存在很多混淆。在迄今为止描述的23个位点中，两个区域Mla和Mlo分别包含约31个和25个等位基因。已有超过50个R基因被定位，超过30个R基因被定位在7条大麦染色体上。最近克隆了4个大麦R基因：Mlo、Rpg1、Mla1和Mla6，并且它们的结构（序列）是可获得的。本文给出了大麦抗性基因符号目录、它们在染色体上的定位以及可用于鉴定品种和育种材料的可用DNA标记列表。
