A renewed interest in
interspecific varieties has recently emerged, due mainly to producers and consumers
more aware of organic farming and impact of phytochemicals in the environment.
The assessment of 19 European Vitis hybrids
was investigated in an area mostly dedicated to viticulture, the North-EasternItaly. Major
agronomic traits, yield, quality characteristics and disease resistance were
evaluated during a three-year period (2004 to 2006). Wine sensory analyses were
performed and compared with international Vitis
vinifera varieties. Even though no genotypes resulted adequate for market release, the results obtained confirm the potential importance of hybrids in an
“eco-friendly” viticulture and identify the genotypes interesting for further
investigation and breeding: GF 138-3 and GA 48-12 showed good agronomic performance, resistance to more grape diseases and high quality wine.
