Cucumber cultivated at Gurye area had viral incidence ranged 9-100% and averaged 48%. The majorly infected viruses were Cucumber green mottle mosaic virus, Zucchini yellow mosaic virus, Papaya ring spot virus and Watermelon mosaic virus-2, and their infection rates were 23.5%, 13.0%, 9.0% and 2.0%, respectively in 2006 and 2007. Mixed infection rate of duplex, triplex and tetraplex was 31.5%, 7.5% and 2.5%, respectively. The rate of infection type was 47.7% by single infection, 31.5% by double infection and 88.7% by both infection types. Important viruses involved in mixed infection types were Zucchini yellow mosaic virus, Cucumber green mottle mosaic virus, Papaya ring spot virus and Broad been wilt virus2, orderly. Symptom in single infection was almost same on ``Dadagi`` line and ``Chicheong`` line of cucumber cultivars.
