Abstract

The influences of rugose wood (RW) disease and grapevine leafroll associated Closterovirus 1 (GLRaV-1) on yield in grapevine cv. Refošk were studied. Both diseases were shown to reduce the yield. The grape quality expressed as sugar degree (°Oe) was higher in GLRaV-1 infected vines probably due to lower yield and consequent early ripeness. 18 % of plants with RW symptoms on the rootstock part of the vine have died 10 years after planting.
