Adaptation, Maturity, and Fruit Quality of Table Grapes in the Intermountain West Region of the U.S.A.

Abstract

Abstract Adaptability, berry maturity and fruit quality of table grapes in the intermountain west region of the United States were studied. Average survival rates were less than 50% for vines of ‘Fantasy’, ‘Flame’, and ‘Red Globe’, but greater than 80% for vines of ‘Alborz’, ‘Concord’, ‘Concord Seedless’, ‘Delight’, ‘Einset’, NY 36095, NY 47616, NY 65.479.1, NY 65.483.2, ‘Pasargad’, ‘Reliance’, and ‘Ruby’. ‘Alborz’, ‘Flame’, and ‘Lakemont’ had heaviest clusters over several seasons. One-year data showed that ‘Emerald’, ‘Exotic’, and ‘Fiesta’ also produced heavier clusters than many other grapes. ‘Canadice’, ‘Concord Seedless’, ‘Glenora’, ‘Interlaken’, NY 65.479.1, ‘Reliance’, and ‘Romulus’ had greatest soluble solids concentrations (SSC). ‘Challenger’, ‘Emerald’, ‘Exotic’, and ‘Italia’ had heaviest berries. Overall, ‘Alborz’, ‘Pasargad’, and ‘Reliance’ had high vine survival rates and high fruit quality ratings (combination of SSC, berry weight, berry tenderness, and/or cluster size). ‘Italia’, ‘Saturn’, and ‘Emerald’ had high overall fruit quality. ‘Alborz’, ‘Pasargad’, ‘Reliance’, and perhaps ‘Italia’, ‘Emerald’, and ‘Saturn’, therefore, are suitable for planting under the conditions of this experiment.
