Variety Harold

Harold (working code IV-6-5-pk) is a table variety from the Potapenko All-Russian Research Institute of Viticulture and Winemaking ((Vostorg × Arkadiia) × Muscat Summer). It ripens very early, in 90–105 days: at the end of July. The cluster is large, cylindrical-conical, of medium density or dense, 500–1000 g. The berries are oval with a pointed tip, amber-yellow, 5–6 g (about 24 × 20 mm). The flesh is fleshy and juicy, the taste harmonious with a light Muscat aroma; sugar content 19–20%, acidity 4–5 g/dm³.

The bush is vigorous, the shoots ripen well, the flower is hermaphroditic. Yields are high (75–80% fruitful shoots, 1.5–1.6 clusters per shoot), so the variety is prone to overloading and needs regulating. Transportability is good. Downy mildew affects it at 3 points, powdery mildew at 3.5, and it is resistant to gray mold. It withstands down to −22 °C, and the vine is covered for winter.
