摘要
China is the largest sweetpotato producer country in the world, with its total growing area and yield reaching 5.5 million ha and 106 million metric tones, respectively. Viral diseases constitute a major hindrance to the development and highly profitable production of the sweetpotato industry. The present article provides updated comprehensive information on type of virus, yield loss caused by viruses, increased yield and benefits by cultivation of virus-free plants. By analyzing data on changes in vegetative growth and physiology of plants infected by viruses, the authors attempted to elucidate the mechanisms by which infection of viruses caused significant losses of the root tuber yield. Meristem culture techniques for production of virus-free sweetpotato plants and propagation system of virus-free seed tubers have been well developed in China. At present time, virus-free sweetpotato seed tubers have been widely used in major sweetpotato-growing areas in China. Usage of virus-free seed tubers has brought great benefits to the sweetpotato industry in China.

中国是世界上最大的甘薯生产国，其总的种植面积和产量达到5500000公顷和1.06亿公吨，分别。病毒性疾病构成的一个主要障碍甘薯产业的发展和高利润的生产。本文章提供了最新的病毒类型的综合信息，由病毒引起的，提高产量和效益的产量损失由种植无病毒的植物。通过分析改变感染病毒的植物营养生长和生理数据，作者试图阐明由病毒感染引起的块根产量损失显著的机制。分生组织培养技术生产脱毒甘薯植物和脱毒种薯繁殖体系已经很发达的中国。在目前的时间，脱毒甘薯种薯已广泛用在中国主要甘薯种植区。脱毒种薯使用已经到了甘薯产业带来了中国很大的好处。
