Grape Breeding and Enology

Welcome to the Grape Breeding and Enology project website!

Located at the University of Minnesota-Twin Cities, we conduct research in the Department of Horticultural Science and at the Horticultural Research Center.  Our focus is on grapevine cultivar development which includes: wine grapes, table grape varieties, and ornamentals that survive and thrive the cold-climate conditions.  We also focus on understanding the mechanisms of disease and pest resistance so that we incorporate these traits as a way to improve sustainability for Minnesota growers.  In addition to developing grapes, we focus on developing and teaching enology best practices for cold-hardy grapes.

Herbicide Recommendations for New Grapevine Plantings

Author: Annie Klodd, Extension Educator.

When planting new grapevines, a strong weed management plan is essential to growing healthy, vigorous, and productive vines. Young vines do not compete well with weeds. Dense weeds in the establishment year will dramatically stunt the growth of the vines and have long term effects like making them weaker, slower to produce a crop, and more susceptible to winter injury. 

Early Season Control of Phomopsis on Grapes

Author: Annie Klodd, Extension Educator

Phomopsis is a prevalent grape disease in Minnesota, and should be sprayed for as part of your early season spray program between bud break and pre-bloom stages. If uncontrolled, it causes brown and black lesions on the canes, black/yellow spots on the leaves, and rot on the ripe berries that can lead to weaker plants and yield loss. Below are some key tips for managing phomopsis:
