Best Table-Grape Varieties for New Hampshire Identified

Scientists with the New Hampshire Agricultural Experiment Station evaluated eight varieties of seedless table grapes to determine which grow best in New Hampshire. The study team reports that ‘Mars’ has performed very well, with consistently high yields, high fruit quality, and relatively good disease resistance. “Seedless table grapes are typically grown in much warmer climates, although several newer varieties released since the 1970s promise increased winter hardiness,” experiment station scientist Becky Sideman said. “Seedless table grapes offer potential for existing vineyards that focus primarily on wine grapes to diversify into additional markets. They also may be a new crop to consider for those who do not currently grow grapes. In particular, the crop management requirements and timing could be compatible with other orchard or berry crops.”
