Abstract:The cucumber green mottle mosaic virus(CGMMV) is one of the quarantine viruses in China which can seriously affect the product of watermelon, melon and cucumber. It has been found in Guangxi,Liaoning,Hebei,Shandong,Guangdong Province and Beijing in China presently. Thus it is important to establish effective methods for the detection of CGMMV. Biology method,serology method,molecular biology method and electron microscopy method are widely used in the detection of CGMMV. This paper made a comprehensive study on the above mentioned methods and pointed out the advantages and disadvantages of these methods as well as the new development of the detection of this virus.
