Brassicae oleracea is an economically important member of the genus Brassica cultivated as an important vegetable crop in Turkey. Field surveys were conducted to determine the virus infection in the various districts of Niğde province during the year 2014-2015. A total of 386 samples were collected from B. oleracea fields and screened using double-antibody sandwich Enzyme-linked immunosorbent assay (DAS-ELISA) to detect Turnip mosaic virus (TuMV), Cauliflower mosaic virus (CaMV), Tomato spotted wilt virus (TSWV), Turnip yellow mosaic virus (TYMV), Radish mosaic virus (RaMV), Beet western yellow virus (BWYV) and Cucumber mosaic virus (CMV). Average cumulative percentage of these viruses affecting plants was 21.76%. The results revealed that 11.91%, 8.80% and 1.03% of the tested samples were infected with TuMV, CaMV and mixed infection with CaMV+TuMV, respectively. However, no sample was found infected with TSWV, TYMV, RaMV, BWYV and CMV. These results indicate that TuMV and CaMV were the only most prevalent endemic viral pathogens of B. oleracea inthe dominantly warm humid continental climate province of Niğde.
