One of the most important factors that affect the yield and quality of vines, grapes and the profit of production are the viruses. The aim of this work is to monitor the occurrence of 4 viruses (GLRaV-1, GLRaV-3, ArMV and GFLV) on 6 table grape varieties: Prima, Black Magic, Cardinal, Demir-kapija, Victoria, Alphonse Lavallée. The research was conducted in the period from November 2019 to September 2020 on one of the larger plantations north of Mostar.Studies have shown different susceptibility of different varieties to these viruses. Of the 60 samples examined, the presence of ArMV virus was not recorded. The presence of GLRaV-1, GLRaV-3 and GFLV viruses was proven by ELISA. The variety Victoria is most susceptible to infection with the GLRaV- 3 virus, in which each sample of this variety is infected. The second variety that is most susceptible is Demir kapija with 80% of infected samples, followed by Cardinal with 70% and Alfonso with 50%. The most resistant varieties according to this research are Prima with 30% of infected samples and Black Magic with 10% of infected samples. Keywords: grapevine, viruses, table varieties, ELISA, symptoms. 1. Introduction The grapevine is one of the oldest and most important cultivated plants. Due to the value of its fruits, today it is present and economically important in almost all countries of the world, where climatic factors allow its cultivation. Vine cultivation is found on almost all continents (except Antarctica), in areas located within a temperate climate zone with clearly separated four seasons. According to data from the International Organization for Vine and Wine (OIV), in 2017, there were 7,534,000 ha under vines, and world grape production amounted to 73,000,000 tons, with a share of 37% in Europe. In Bosnia and Herzegovina, more than 95% of the area under vines is located in the southern regions of Herzegovina, mostly in private ownership. However, viticulture in BiH is developing more and more quickly and is becoming, apart from the traditional, also in the economic sense, a very important branch of the economy. That is why it is important to understand and investigate all the factors that can disrupt the process of growing vines and the production of grapes and wine. One of the most important factors that affect the yield and quality of vines and grapes, as well as the profits of agricultural farms, are viruses that are the subject of research. Diseases caused by phytopathogenic viruses are a limiting factor in the profitable production of grapevines. Grapevine is the crop parasitized by the largest number of plant viruses, more than 70 of them, specific or non- specific for grapevine, which have been investigated in the past 60 years (Meng et al., 2017). In addition to reducing the yield in the quantity and quality of grapes, the negative impact of viral diseases can also be reflected in the reduction of the vitality of the vines, which directly affects their resistance to adverse external conditions, primarily low temperatures, and shortens the exploitation life of the vineyard. Great difficulties can also be caused in the production of reproductive material through a reduced rooting ability of vine grafts, as well as weaker fusion or incompatibility of podolog and scion (Ristić et al., 2018).
