摘　　要：为了研究小麦梭条花叶病病毒的致病力及其与品种(系)抗病性的互作关系,应用采集自江苏苏州、江宁、兴化、宜兴和六合五个不同地区的小麦梭条花叶病病土,测定了30个小麦品种(系)在上述病土中的发病情况。结果表明,30个小麦品种(系)对梭条花叶病毒的抗性表现为3种类型即广谱抗型、部分抗型和广谱感型;小麦梭条花叶病毒致病力有明显的区域性差异,存在着显著的致病力分化现象;病毒致病力和品种(系)间存在互作效应。Diseased soil of wssm from different counties were examined by 30 wheat varieties. The result showed that resistance of wheat varieties to wssm can be divided into three types： broad-spectrum resistance, broad-spectrum susceptibility and partial resistance. The pathogenicity of WSSM has significant regional differences. There is interaction between pathogenicity of WSSM and resistance of wheat varieties.
