(http://www.addthis.com/bookmark.php?v=300&pubid=ra-4fdf78bc4ba1b534)Tuesday, September 5, 2017DURHAM, N.H. – University of New Hampshire researchers have found certain varieties of seedless table grapes grow better in New Hampshire’s colderclimate than others.The research project, funded by the New Hampshire Agricultural Experiment Station (http://colsa.unh.edu/nhaes/), aims to determine which varieties ofseedless table grapes are best suited to New Hampshire production, and to determine which growing systems are best suited to those varieties. The resultsare particularly relevant to growers in New Hampshire and northern New England.The new research was conducted by experiment station researcher Becky Sideman, extension professor of sustainable horticulture production, and GeorgeHamilton, extension field specialist.“Seedless table grapes are typically grown in much warmer climates, although several newer varieties released since the 1970s promise increased winterhardiness,” said Sideman. Hamilton collaborated with vineyard owner John Lastowka in Merrimack to conduct a preliminary trial, and the best varieties wereselected for the UNH research vineyard.Eight varieties of seedless table grapes that were planted in a vineyard at Woodman Farm in May 2015 are being evaluated: Canadice, Concord Seedless, Lakemont, Marquis, Mars, Reliance, Thomcord, and Vanessa.Now in their third year, all varieties are producing fruit.Most varieties had 100 percent winter survival and showed good vigor during summer. However, three varieties -- Thomcord, Lakemont, and Marquis – experienced some winter mortality and poor vigor. The highestmortality and lowest vigor was observed for Thomcord, while Lakemont and Marquis had intermediate mortality and vigor.Researchers have been taking note of how the di erent varieties respond to common grape disease, such as anthracnose, downy mildew, and powdery mildew. In 2016, all of these diseases were present in thevineyard. Some of the varieties, such as Canadice and Concord Seedless, remained relatively symptom-free in the face of all three diseases, whereas other varieties appeared to be especially susceptible to certaindiseases. Lakemont and Thomcord were particularly susceptible to downy mildew, and Marquis was highly susceptible to both downy and powdery mildew as well as to anthracnose.This material is based upon work supported by the NH Agricultural Experiment Station, through joint funding of the National Institute of Food and Agriculture, U.S. Department of Agriculture, under award number1006928, and the state of New Hampshire. This work also was supported by the NH Department of Agriculture, Markets & Food through NH Specialty Crop Block Grant 14-SCBGP-NH-0033.
