Several hardy seedless grape cultivars have been released within the last few decades. We have recently planted a research vineyard at the Agricultural Experiment Station in Durham, NH to compare eight table grape cultivars under two training systems: vertical-shoot positioning (VSP) and modified Munson (MM).
Our Objective: To identify table grape varieties that are well suited to production in NH, and to determine the optimum training system for these varieties. We have prepared a preliminary report that includes data on susceptibility to diseases, as well as yield and fruit quality information from 2019, the fifth year of growth.
