All grapevine samples were serologically investigated for the presence of Grapevine leafroll-associated viruses (GLRaVs) using GLRaV-1, GLRaV-2, GLRaV-3, GLRaV 4-9, GLRaV-6 and GLRaV-7 DAS-ELISA kits. In 143 of total, (67.14%) single or multiple infections were detected. GLRaV4-9, -7, -3, -1, -2 and -6 were detected as 53.52%, 36.15%, 34.74%, 32. 86%, 32.39% and 3.28%, respectively in the surveyed area. Eastern Anatolia Region had the highest infection rate (100%), followed by Marmara, Aegean, and Central Anatolia Region (69.74%, 75%, 62% and 26.47%, respectively). While the highest infection rates were obtained in Marmara Region for GLRaV-1, -2 and -3 as 43.42%, 44.74% and 50% respectively, GLRaV4-9 found as 100% in Eastern Anatolia Region. The highest infection rate was detected in Marmara Region for GLRaV-6 as 3.95%. The most common multiple infection was determined as GLRaV-1, -2, -3, 4-9 and -7 with the rate of 36.17%.
