RT Journal Article SR Electronic T1 Field Performance and Wine Quality Modification in a Clone of Vitis vinifera cv. Dolcetto after GLRaV-3 Elimination JF American Journal of Enology and Viticulture JO Am. J. Enol. Vitic. FD American Society for Enology and Viticulture SP 144 OP 147 DO 10.5344/ajev.2011.11020 VO 63 IS 1 A1 Franco Mannini A1 Alessandra Mollo A1 Rino Credi YR 2012 UL http://www.ajevonline.org/content/63/1/144.abstract AB Grapevine leafroll is one of the most widespread virus diseases of grapevine and Grapevine leafroll-associated virus 3 (GLRaV-3) is one of its major causal agents. The effect of GLRaV-3 elimination was studied under vineyard conditions for two years by comparing the virus-free and infected lines of the same clone of Vitis vinifera cv. Dolcetto, an important red wine cultivar grown in northwestern Italy. The results confirmed the advantages of using virus-free vines in terms of field performance (vigor, yield, leaf photosynthesis, and juice soluble solids), whereas the advantages in wine quality were less evident. Sensory analysis clarified that the wine from virus-free vines was slightly different from that of vines infected by GLRaV-3, but did not indicate a significant preference for one or the other.
