Grapevine Super Early Bolgar - White Dessert Grape, Earliest Ripening

The variety was obtained by crossing Italia x Yantar in 1961 at the Institute of Viticulture and Enology - Pleven by K. Stoev, Y. Ivanov, Z. Zankov and V. Valchev. Agrobiological characteristics: Belongs to the group of the earliest varieties (the grapes ripen in the first days of August). The bunch is medium to large, conical, moderately compact, conical or winged with one wing. The berry is large to very large, elongated, covered with a thin, tough, yellow-green to amber skin. The variety is prone to poor fruit set and shot berries (millerandage). Under irrigated conditions the vines have good affinity with rootstock SO4.   Technological characteristics: The grapes contain on average about 15-16% sugars with a titratable acid content of 5-6 g/l.  Resistance - the vines are sensitive to powdery mildew, downy mildew and low winter temperatures. The grapes are practically resistant to grey mould. Yield - the vines are vigorous with good fertility and productivity (the average yield per vine is about 6 kg, and per decare - 1000-1500 kg). The grapes are distinguished by good transportability.
