小麦黄花叶病毒病是危害我国冬小麦的一种重要病害，为明确山东小麦生产品种对该病害的抗性水平，给山东小麦黄花叶病毒病育种、病害防控及品种合理布局提供参考信息，于2012-2015年在山东省莒南县板泉镇的小麦黄花叶病毒病品种抗病性鉴定圃，对山东80个小麦生产品种进行了抗性评价和产量性状分析。结果表明，在供试的80个小麦品种中，济麦22、烟农5158、鲁原231、鲁原304、良星99、烟农0428、烟农173、烟农999、阳光10、红地09-5、山农18、山农29、烟农426、烟农836、济南17共15个品种对小麦黄花叶病毒病表现为抗病，占供试品种的18.75%；烟农24、鲁原502、济麦21、泰农1014等31个品种表现中抗，占供试品种的38.75%；其余34个品种表现为感病，占供试品种的42.5%。感病品种产量的损失率与有效穗数、穗粒数、千粒重3因素的综合损失率密切相关。

英文摘要:

Wheat yellow mosaic virus(WYMV) disease is one of the most important threats to winter wheat in China. In order to evaluate the resistance to WYMV of wheat cultivars and provide the reference values for the breeding,disease prevention and control,and reasonable layout of wheat variety cultivation in Shandong province,the resistance evaluation and yield-related traits analysis of wheat cultivars were studied in a disease nursery at Banquan town,Junan,Shandong province from 2012 to 2015. The results showed that 15 cultivars including Jimai 22,Yannong 29,Luyuan 231,Luyuan 304,Liangxing 99,Yannong 0428,Yannong 173,Yannong 999,Yangguang 10,Hongdi 09-5,Shannong 18,Shannong 29,Yannong 426,Yannong 836 and Jinan 17(18.75% of the 80 tested cultivars) were resistant to WYMV; 31 cultivars including Yannong 24,Luyuan 502,Jimai 21,Tainong 1041 and other cultivars(38.75% of tested materials) were moderately resistant; and other 34 cultivars(42.5% of tested materials) were susceptible to WYMV. The results of yield determination and loss rate analysis in 30 cultivars showed that wheat yield loss rate was closely related to the loss rates of spike number,grains per spike and 1 000-grain weight.
