甘蔗白叶病(SCWL)是一种易随种苗进行远距离传播的危险性检疫病害。近年我国从缅甸、菲律宾和法国等国引进的甘蔗品种/材料SCWL植原体阳性检出率高达78%,存在严重的引种安全隐患。云南省农业科学院甘蔗研究所选择15个经巢式PCR检测确认带有SCWL植原体的引进甘蔗品种/材料进行温 Sugarcane leaf disease (SCWL) is a dangerous quarantine disease that can easily spread with seedlings over long distances. In recent years, the positive rate of detection of SCWL phytoplasma in sugarcane varieties / materials introduced from Myanmar, the Philippines and France has reached as high as 78%, which poses a serious threat to the introduction of safety. Sugarcane Institute of Yunnan Academy of Agricultural Sciences selected 15 nested PCR assays to confirm the introduction of sugarcane varieties / materials with SCWL phytoplasmas for temperature
