Grape Lyana

Lyana is a white table grape variety of early-mid ripening period, bred at the Agrarian University of Moldova through crossing the Chaus white and Pierreil varieties. The clusters of this variety are medium-sized, conical, weighing from 295 to 400 grams, with dimensions of about 16 by 12 centimeters. They are of medium density and well-formed, which ensures increased resistance to tortrix. The berries are medium and large in size, weighing about 4.5 grams, egg-shaped, pale yellow-green in color with possible sunburn. The taste is pleasant, with floral notes, confirmed by a high tasting score of about 8.1 points. The variety is characterized by high yield — on average over three years of fruiting it is about 190 centners per hectare. Lyana has good vigor of bushes and good vine ripening. It is relatively drought-resistant but not winter-hardy. An important feature is high resistance to major diseases and pests: downy mildew, spider mites, gray rot of berries, powdery mildew, and phylloxera. However, under unfavorable weather conditions during flowering, partial drying of flowers or inflorescences may occur, which may reduce yield. The variety also has a predisposition to bacterial cancer. Lyana is characterized by high commercial quality and good transportability, which makes it attractive for commercial growing and marketing. The fruiting and bearing coefficients are at the level of 1.6 and 1.7, respectively, indicating stable and quality fruiting. Sugar accumulation reaches 14 percent, acidity about 6.5 g/l, which ensures a harmonious taste of berries. Affinity with rootstock varieties is good, which facilitates the use of Lyana in viticulture.
