马铃薯Y病毒(PVY)已再次成为马铃薯种薯生产的严重障碍，导致产量和块茎品质下降，以及由于病毒发病率过高而被认证计划拒收的大部分种子批次。这导致了种子短缺，特别是在高度易受感染的品种中。虽然种子认证计划在低于经济门槛的情况下有效地管理了许多病毒疾病，但PVY在近几十年来迅速演变为一种复杂的菌株，可以逃避许多认证和农场管理实践。PVY菌株的进化是自然发生的，但几种人类影响可以与影响马铃薯作物的PVY种群的快速变化联系在一起。在这里，我们重点介绍了马铃薯PVY病毒的近期历史和现状，并提出了一些未来管理病毒的方法。
Potato virus Y (PVY) has reemerged as a serious impediment to seed potato production, responsible for reduced yields and tuber quality, as well as the majority of seed lot rejections by certification programs due to excessive virus incidence. This has led to seed shortages, especially in cultivars highly susceptible to infection. While seed certification programs have been effective at managing many virus diseases below economic thresholds, PVY has rapidly evolved in recent decades to become a complex of strains that evade many certification and farm management practices. The evolution of PVY strains is naturally occurring, but several human influences can be linked to the rapid change in PVY populations affecting the potato crop. Here we highlight the recent history and current status of PVY in potatoes and suggest some approaches for managing the virus moving forward.
