摘　　要：病毒病是甘薯的重要病害,种植脱毒健康种苗是防治病毒病、提高甘薯产量最有效的方法。近年来,我国甘薯病毒及其传播介体的发生呈现出新的特点,传统的脱毒种薯种苗繁育体系不能满足当前甘薯生产的需要。本文综述了当前我国甘薯病毒的种类及危害现状,分析了我国甘薯脱毒种薯种苗繁育中存在的问题,对规范和完善我国甘薯脱毒种薯种苗繁育体系提出了建议。Viral diseases are important diseases threatening sweet potato production in China.The most effective measure for controlling viral diseases and improving the yield of sweet potato is planting virus-free sweet potato seeds(cuttings or storage roots).In recent years,the occurrence of sweet potato viruses and their transmission vectors has exhibited new features in China.Traditional virus-free seed breeding system cannot meet the needs of the current sweet potato production.The species and harm status of sweet potato viruses in China were reviewed,and the problems in the breeding of virus-free sweet potato seeds in China were analyzed.The suggestions for standardizing and improving the breeding system of virus-free sweet potato seeds in China were offered.
