摘要
用国际马铃薯中心提供的可检测6种甘薯病毒病血清检测试剂盒,采用NCM-ELISA方法,对皖北甘薯主栽品种及脱毒苗等1248个样进行了检测。结果表明:徐薯18、皖薯1号、553、7-3、鲁薯7号、丰产1号、皖薯6号7个品种对6种病毒病血清均呈不同程度的阳性反应。其中以SPFMV带毒率为37.02%,SPLV为18.27%、SPMMV为8.65%,C-2为14.42%,C-8为13.46%,C-6为10.01%。脱毒核心原原种苗不带毒,脱毒一二代苗及新品种皖薯6号只带SPFMV病毒。巴西牵牛嫁接法与血清检测法结合应用可达到简单易行、规范化、标准化的目的。脱毒甘薯种植2~3a后必须更新。
The serum reagent box may
measure 6 sweet potato viruses and was introduced from the International Potato
Center(CIP).1248 samples of major sweet potato varieties and virus-free plantlets were
identified by the method of the NCMELISA assay in northern Anhui.The experinent results
showed that Xushu 18,Wanshu 1,553,73,Lushu 7.Fengchan 1 and Wanshu 6 etc.varieties were
positive reaction in varying degrees for six virus serums.The viruliferous percentage of SPFMV,
SPLV,SPMMV,C2,C8 and C6 were 37.02%,18.27%,8.65%,14.42%,13.46% and
10.01%,respectively.The first and second generation of virus-free plantlets and new
varietyXushu 6 only carried SPFMV,but the virusfree original seedlins were without virus.The
methods of Brazilian Morningglory(Ipomoea setosa)grafting in combination with serum
eramination was simple,convenient and standardization.Virusfree plantlets must be renewed
after 2 or 3 years growth.
