引进甘蔗品种（材料）检疫及重要病害检测

摘要

Disease epidemic and insects damage were not discovered through observing inspection on 36 sugarcane varieties from Philippines, Thailand, Burma and Kampuchea within two growth cycles in Yunnan Kunming quarantine greenhouse according to quarantine program of international standards. Furthermore, molecular detection of five quarantinable sugarcane disease, i.e., Sugarcane White Leaf （SCWL）, Fiji Disease, Mosaic, Leaf Scald and Ratoon Stunting Disease （RSD）, were fulfilled by using established molecular detection system. The detection results showed that all sugarcane varieties were negative but eight varieties were positive on RSD. The positive ones were meanwhile isolated to secure international sugarcane varieties exchange.%按照国际标准检疫程序对从菲律宾、泰国、缅甸、柬埔寨等亚洲国家引进的36个甘蔗品种（材料）于昆明甘蔗检疫温室进行了病害疫情监测，未发现疫情；并利用已建立的分子检测技术对甘蔗斐济病、花叶病、白条病和宿根矮化病等4种重要病害进行了检测，结果有8甘蔗品种（材料）宿根矮化病呈阳性，其余均呈阴性。同时对呈阳性的甘蔗品种（材料）进行了隔离处理，从而确保了国际合作甘蔗品种交换的顺利开展。
