Control of grapevine virus diseases in collections and at the stages of propagation in Ukraine

Abstract

The principles of virological control on different types of grapevine collections and plantations  are summarized. Grapevine leafroll virus  was most often detected on all studied types of collections and plantations. The lowest risk of virus infection  detecting  was in the clone repository, the highest in the ampelographic collection, clonal trial plots of the first vegetative progeny and in industrial vineyards where clonal selection is carried out. A trend of influence of temperature and humidity regime indicators on the number of plants with symptoms of grapevine leafroll was revealed. The correlation coefficient R2 between the number of plants with symptoms of grapevine leafroll and indicators of temperature and humidity regime ranges from 0.69 to 0.77.
