Özet

Grapevine (Vitis vinifera L.) is one of the most important fruit crops in Turkeyand viral diseases are one of the main problems of grapevine production. Theydecrease yield quantity and quality of crops as well as cause death of the plantsin an interaction with other agents. Leafroll disease of grapevine, caused by acomplex of viruses, is considered a serious threat to production across manygrapevine growing regions in Turkey. This study was conducted to determinethe current status of Grapevine leafroll-associated viruses (GLRaVs) in Malatyaprovince. Grapevine plantations in Malatya province were surveyed for thepresence of Grapevine leafroll-associated viruses (GLRaVs) -1, -2, -3, -4 and -6.Purposive sampling was done in vineyards of Arapgir, Darende and Battalgazidistricts, which are the primary grapevine producing areas of Malatya during2016-2017 growing seasons. A total of 241 samples were collected and tested byDAS-ELISA. Samples giving two fold of absorbance values (405 nm) of negativecontrol were evaluated as positive. According to the results, 131 samples werefound to be infected with GLRaV-1, whereas 48 samples with GLRaV-3 and -4samples with GLRaV-4. None of the samples were reacted as positive againstGLRaV-2 and GLRaV-6. Forty five samples were found to be infected with mixinfection of GLRaV-1 and -3, and three samples were found to be infected withGLRaV-1 and -4 strain 6.
