病毒退化是马铃薯生产上长期存在的主要问題。病毒侵染不仅严重影响马铃薯生产,而且直接影响新品种选育,使许多具有优良经济性状和农艺性状的材料在选育初期就失去了利用价值。选育抗病毒品种是防治马铃薯病毒病最为经济、有效的措施,但目前选育抗病毒品种中普遍采用的田间鉴定法费时费工且误差较大。因此,在马铃薯F_1实 Virus degeneration is a long-standing problem in potato production. Virus infection not only seriously affects the potato production, but also directly affects the selection and breeding of new varieties, so that many materials with excellent economic and agronomic traits lose their value in early breeding. Breeding anti-virus varieties is the most economical and effective measure to prevent and control potato virus diseases. However, field identification methods widely used in breeding anti-virus varieties are time-consuming and labor-intensive. So potato F_1 is solid
