摘　　要：大豆花叶病毒病(Soybean mosaic virus disease,SMV)是大豆生产的主要病害之一,应用抗病品种是控制该病最经济有效的方法。野生大豆抗SMV机制的探讨是大豆抗病育种的重要基础。通过人工接种和田间自然发病鉴定方法,对来源于河北东部沿海地区的129份野生大豆材料进行抗SMV鉴定及叶片形态结构的比较。结果表明,2.3%的材料抗大豆花叶病毒病,14.7%的材料表现为中抗,26.4%的材料表现为中间反应类型;不同抗感野生大豆材料的叶片蜡质含量及茸毛密度存在明显差异,相关分析表明蜡质含量与野生大豆对病毒病的抗性呈显著正相关。因此,叶片蜡质含量可作为野生大豆材料病毒病抗性鉴定的参考指标。Soybean mosaic virus disease（SMV） is one of the most important diseases of soybean. Growing resistant cultivars has proved to be an economical and effective approach to control this disease. Resistant mechanism of wild soybean to SMV is principal for soybean resistant-disease breeding. Resistance of 129 wild soybean materials from the eastern coastal region of Hebei province were identified through artificial inoculation test in pots and natural infection test in field. Among the materials tested,2.3% wild soybean materials were resistant, 14.7% wild soybean materials were mid-resistant, and 26.4% of them were intermediate. There were obvious differences in wax content and hair density of these materials with different resistance levels, and the wax content of wild soybean was correlated with its resistance of SMV significantly. Therefore, wax contcnt could be used as one of indexes for indentification of wild soybean resistan to SMV.
