The Northern Grapes Project was funded in 2011 by the USDA NIFA Specialty Crops Research Initiative.  The emergence of cold hardy, Vitis riparia-based wine grape cultivars in the 1990s created a new and rapidly expanding industry of small vineyard and winery enterprises in more than 12 states in New England, northern New York, and the Upper Midwest, boosting rural economies in those regions.  Read more.

“Impact of training systems on viticulture performance of cold-hardy wine grapes”

Amaya Atucha, Paolo Sabbatini and Madeline Wimmer

*Wednesday*, March 22nd, 2017

12:00 Noon Eastern (11:00 am Central)

7:00 pm Eastern (6:00 pm Central)

With Amaya Atucha, Paolo Sabbatini, and Madeline Wimmer

This seminar will present research results from a trial in southern Wisconsin on the effect of three training systems: vertical shoot positioning, Scott-Henry, and high wire cordon on the viticulture performance of four cold-hardy grape cultivars: Marquette, Frontenac, La Crescent, and Brianna.  Amaya Atucha is an assistant professor of horticulture at the University of Wisconsin-Madison, where she has a research and extension program in fruit crops focused on production practices to increase sustainability and fruit quality.  Madeline Wimmer is a graduate student at UW-Madison in the Atucha group.  Paolo Sabbatini is an associate professor of horticulture at Michigan State University.  He has research and extension responsibilities in viticulture, and he has evaluated wine grape cultivars to optimize vine productivity and quality for the Northern Grapes Project.
