abstract = "Grapevine leafroll associated viruses (GLRaV) in the family of Closteroviridae are the most widespread and dangerous viral pathogens of severe grapevine viral infection - Grapevine leafroll disease (GLD). Among this viruses GLRaV-1 and GLRaV-3 are the main causative agents of GLD. Economic impact of grapevine viral agents can be dramatic for the grape industry. Only a limited number of viruses infecting grapevine have been identified in Georgian vineyards which is the ancient and one of the main wine-producing region. It is important to focus on increasing the quality of wines produced from the widely distributed indigenous grape varieties in Georigan vineyards such as white-berried cultivar-Rkatsiteli and red-berried cultivar-Saperavi in order to produce wine that meets international quality standards. Main goals of the proposed study were to determine which member of Grapevine leafroll associated viruses is prevalent in Georgian vineyards also application of serological methods for the detection of different serological groups of the viruses. Sampling for the detection of GLRaV-1 and GLRaV-3 viruses was conducted from Rkatsiteli and Saperavi grapevine cultivars growing in vineyards located in traditional wine-producing region Kakheti, the east part of Georgia. A total of 600 samples (300-Rkatsiteli and 300 Saperavi) were collected and analyzed from twenty different locations during 2016-2017 growing seasons. The study showed the distribution of GLRaV-1 and GLRaV-3 as either single or mixed infections. Virus profiles were determined for individual vines. The overall analysis showed that GLRaV-3 virus was the prevalent also mixed infections were found when the grapevine was infected with both of the viruses. Viral disease control strategies that involves the use of virus-free planting material for further propagation in nurseries from tested vines by use of comprehensive laboratory assays will be the outcome in order to be sure in quality of new plant material.",
