Abstract
  • Many winemakers and viticulturists will be aware of the negative effects of Grapevine LeafRoll associated Viruses types 1 and 3 (GLRaV-1 and GLRaV-3) upon fruit quality, especially in the more sensitive red varieties. Few people are aware of the effects of GLRaV-2 and its associated variants. GLRaV-2 is known to be associated with graft incompatibility problems, and the combination of GLRaV-2 and some other viruses resulting in such incompatibility problems is a topic being extensively researched at the University of California at Davis (Golino et al., 1993, 2003). In New Zealand, the only reported findings of GLRaV-2 so far concern the Bordeaux clones of Sauvignon Blanc, 316 and 317, and we have observed incompatibility reactions with these clones when grafted onto some rootstock varieties. The Alfie virus appears to be a variant of GLRaV-2 and also produces similar incompatibility problems with some rootstocks. Another recently reported virus, the Grapevine Rootstock Stem Lesion associated Virus (GRSLaV) (Uyemoto et al., 2001; Rowhani et al., 2002) appears to be another variant of GLRaV-2. Our molecular genetic studies on the Alfie virus so far have given us genetic sequence data on three important viral genes in the Alfie virus, and the closest relative we can find for this virus is GRSLaV. The next most closely related virus to the Alfie virus after GRSLaV is GLRaV-2. GRSLaV can cause severe incompatibility problems on susceptible rootstocks (Uyemoto et al., 2001), and while it was first found in the table grape variety \"Red Globe\" it has more recently also been found in some wine grape varieties.
