For the detection of tobacco mosaic virus (TMV), tomato mosaic virus (ToMV) and cucumber mosaic virus (CMV), tomato seeds of 11 table tomato and 7 cherry tomato cultivars were assayed by DAS-ELISA. Among the cultivars, TMV and ToMV were detected from 9 cultivars at the rates lower than 20 and 16%, respectively. In the assay on seed transmission rates, ToMV and CMV were detected as high as 24 and 8%, respectively, but TMV was not detected. In field survey on these viruses from tomato plants of 10 different places in Chungbuk province, Korea Republic, ToMV and CMV were detected from most fields, whereas TMV was detected from only 3 fields. The highest detection rates of these viruses were recorded in Cheongwon for TMV, Chungju for ToMV, and the other locality of Chungju for CMV. It was difficult to find any relationship between the growth stage of tomato and infection rates. TMV usually caused mosaic on leaves, while ToMV caused various symptoms including yellows, necrosis and mottling. CMV-infected tomato plants showed symptoms of shoestring, fern leaf and yellows.
