摘　　要：大豆胞囊线虫病是一种世界范围内的大豆病害,严重影响大豆产量和品质,给大豆生产造成极大的危害。了解大豆胞囊线虫的致病过程,阐明抗病大豆品种的抗性机制,分离抗病基因,并通过现代分子育种技术改良和筛选抗胞囊线虫病大豆新品种,是解决胞囊线虫危害的有效方法。综述了大豆胞囊线虫的生理生化特征、危害症状、生理小种划分以及大豆胞囊线虫抗性机制、遗传基础和抗性相关基因的研究进展。Soybean cyst nematode （SCN） is the most devastating disease to soybean production, which causes a great economical loss worldwide. Understanding the SCN pathogenesis and SCN-resistant mechanism, isolating the resistance genes to SCN, as well as selecting and improving SCN-resistant soybean varieties through molecular breeding techniques are effective ways to reduce the SCN damage. Herein, the research progress on the physiological and biochemical characteristics ,the symptoms ,and the physiological race classification of SCN, as well as the SCN- resistant mechanism in soybean, their genetic basis and resistance-related genes were reviewed.
