Presence and Distribution of Grapevine Leafroll-associated Virus 1 and 3 in Bosnia and Herzegovina
Abstract
There are over 50 different viruses and virus-like diseases infecting grapevines throughout the world. Viruses from the genera Ampelovirus and Closterovirus are causal agents of the most widespread disease known as grapevine leafroll (Grapevine leafroll virus, GLRV).There are currently nine different viruses associated with leafroll, but Grapevine leafroll-associated viruses 1 and 3 (GLRaV-1, 3) are the most commonly found.The most appreciated native grapevine cultivars in Bosnia and Herzegovina (B&H) were chosen as objects of this research project. The Institute of Fruit Growing, Viticulture and Ornamental Plants in Banjaluka has started investigations in order to establish the phytosanitary status of grapevine in B&H. This investigation therefore aims to determine the presence and evaluate the distribution of GLRaV-1 and GLRaV-3 on local grapevine varieties.In October 2006, surveys of young and old vineyards were carried out in several localities in western and eastern parts of Herzegovina. Symptomatic and symptomless plants were sampled. All analyses were done in the Institute laboratory using ELISA test.The results enable new approaches and provide information about the presence and distribution of GLRaV-1 and GLRaV-3 on native grapevine cultivars in B&H.
