摘　　要：[目的]分离获得与鉴定引发杂交水稻稻曲病的病原真菌。[方法]通过微生物培养方法及多相分类鉴定技术,对引发杂交水稻稻曲病害的病原真菌进行分离与鉴定。[结果]该研究分离获得了引发稻曲病病害的绝对优势病原菌种,并鉴定为稻绿核菌(Ustilaginoidea virens)。[结论]该研究为进一步防治水稻稻曲病病原真菌与减少稻曲病病害发生奠定了科学基础。[Objective] To isolate and identify the pathogenic fungi that would cause hybrid rice false smut.[Method]To isolate and identify the pathogen strains of false smut from hybrid rice by the methods of microorganism cultivation and polyphasic taxonomic technology. [Result]In this study,the absolutely dominant pathogenic bacteria that caused the disease of rice smut was isolated and identified as Ustilaginoidea virens.[Conclusion] This study laid a scientific foundation for further prevention and control on rice fungal pathogens and reduction of rice smut disease occurrence.
