Multi-State Evaluation of Wine Grape Cultivars and Clones

Department of Horticulture

 

Non-Technical Summary

Grapevine nurseries, grape growers, and vintners would be more competitive both within their region or production area and in the international market. The environmental impact of wine grape production would be reduced by identifying disease and pest resistant cultivars and cultivars. Alternative cultivar/product options would be created for areas where traditional cultivars and markets have declined. Our national grape importation program would be enhanced by evaluation data that would improve our ability to judge the potential impact of introducing individual accessions. Grape breeding and selection programs would be more efficient due to a better understanding of grape and wine genotype X environmental interactions and nature of clonal variation. To identify wine grape cultivars and clones suited to sustainable production in various cooperating states.

2010 Project Description

Vines planted in the spring of 2006 and 2008 as part of the NE1020 Multi-state Evaluation of Wine grape cultivars and clones were maintained according to the established NE1020 protocol. Cultivars planted in 2006 include Cabernet Sauvignon (#08), Chambourcin, Frontenac, Corot Noir, NY76.0844, Vidal Blanc, and Vignoles. Cultivars planted in 2008 include, Malbec, Petite Verdot, Pinot Noir (#13), Rkatsitelli, Tinto Cao, Touriga Nacionale, Frontenac Gris and Marquette.

2010 Impact

Vines planted in both 2006 and 2008 expressed moderate vigor and are expected to have a nearly full canopy during the 2011 season. To date significant winter injury in the 2008 planting has been observed on Cabernet Sauvignon and Touriga Nacionale vines with minimal damage to: Malbec, Petite Verdot, Pinot Noir, Rkatsitelli, and Tinto Cao.
