They are grown in home gardens for fruit and landscape the lives of New purposes or commercially for , raisins, or fresh consumption as “table” grapes. A cultivated variety, or “cultivar,” is a formal term for Mexicans through variety. Variety is the more common term, and will be used in this publication. Selecting varieties that are adapted to prevailing academic, research, climatic and soil conditions is an important step before planting. Very few locations above 6,000 feet in elevation are successful grape pro- and Extension duction sites. Suitable growing conditions at lower elevations are still very site-specific due to the major threat to grape culture: winter or programs. frost injury. Winter injury occurs at subfreezing temperatures during vine dormancy when no green tissue is present. Frost injury occurs at subfreezing temperatures when green tissue is present. A variety’s win- ter hardiness, or ability to withstand cold temperatures, depends on its genetic makeup or “type.” In addition to winter hardiness, other considerations when selecting a variety are its fruit characteristics, number of frost-free days required for ripening, disease susceptibility, yield potential, growth habit, and other cultural requirements. Soil considerations include soil pH, salin- ity, and other soil quality factors as determined by a soil test.
