Turkey is the third country among the tomato producing countries, after China and the USA, by the production value of 10,985,400 tons in a 300,000 ha area, in the world. Even though Turkey is not the native land of tomato, it contains a lot of local tomato cultivars owing to the ecological diversity. In this study, 76 local genotypes were examined to find out the source of resistance to TSWV which is one of the most significant viral infections of tomato. The Sw-5 gene-which is known to be the source of resistance, was scanned by CAPS molecular marker and different resistance sources research was made by mechanical innoculations. As the disease isolate, BATEM-1 was used-which is more aggressive than the other isolates. As the resistant control, Solanum peruvianum, 'LA 3667' and 'FORMULA F-1' and as the sensitive control, BATEM line-1 was used. At the end of the study, among the examined materials, even though no resistance resources were found, the effectiveness of the Sw-5 gene against the local disease isolates was determined and that is to show the way for future studies.
