However, specificity and sensitivity of them may show variation according to pathogens and hosts. In this study, Grapevine fanleaf nepovirus insert ignore into journalissuearticles values(GFLV); which was the most prevalent viral agent in Aegean viticulture production areas was used to compare conventional RT-PCR and real-time RT-PCR. For this purpose, 8 infected and 5 healthy, totally 13 symptomatic grapevine samples which have been detected by DAS-ELISA were used. After the conventional RT-PCR and real-time PCR assays, results were evaluated agarose gel electrophoresis and melting analysis respectively. The conventional RT-PCR results showed that 10 out of 13 samples were infected with GFLV, whereas 11 out of 13 samples were found infected with real-time RT-PCR. At the end of this study, the real-time RT-PCR assays were found more sensitive, reliable and rapid than conventional RT-PCR.
