The Cucurbitaceae are a plant family that consist of over a hundred genera, the most important of which are squash, pumpkin, zucchini, some gourds, cucumber and watermelon. These are among the top imported seeds in Korea. At the time of their import, the Squash mosaic virus (SqMV), the Cucumber green mottle mosaic virus (CGMMV) and the Kyuri green mottle mosaic virus (KGMMV) are designated as regulated viruses for quarantine in Korea. This study was conducted to develop specific primer sets for easy and rapid detection of SqMV, CGMMV and KGMMV. RT-PCR with the nested PCR primer sets and modified positive control plasmids were capable of highly sensitive detection and verification of such viruses. In addition, developed diagnostic PCR systems applied to quarantine sites detected 47 cases of SqMV, 67 cases of CGMMV and 17 cases of KGMMV between 2010 and the first half of 2014.
