The grape, like many fruit crops, is quite sensitive to low temperatures. The U.S. grape crop is reduced an estimated 10% annually by late spring freezes alone (10). Climatic conditions greatly limit the geographic distribution of grape species and cultivars. In the eastern U.S., Vitis labruscacultivars predominate with the Concord cultivar accounting for over 80% of the production (2). V. viniferagrapes that are rather winter tender are increasing in acreage (1, 5, 7). French hybrids which have labrusca, vinifera, and other species in their parentage are intermediate in hardiness and are also rather widely planted in this region.
