Detection of Grapevine rupestris stem pitting-associated virus in the vineyards of Southeastern Anatolia and Eastern Mediterranean in Turkey

In this study, it was aimed to survey the vineyards for the presence of the Grapevine rupestris stem pitting-associated virus (GRSPaV) in the Southeastern Anatolia (Gaziantep, Adıyaman and Kilis) and Eastern Mediterranean Region (Kahramanmaraş, Hatay, Adana and Mersin) with a newly designed primer pair. A total of 381 samples from 96 vineyards were collected and analysed by RT-PCR technique. Of the 381 samples collected, 40 were found to be infected with GRSPaV. The prevalence rates of GRSPaV were respectively calculated as follows: Kahramanmaras (4.46%), Kilis (2.36%), Adıyaman (1.58%), Gaziantep (1.31%), Adana (0.53%), Mersin (0.26%) and Hatay (0%). As a result, it has been determined that the virus has a significant prevalence in Southeastern Anatolia and Eastern Mediterranean Region
