Variety Valentina

Valentina (working code IV-8-7-ppk) is a table variety from the Potapenko All-Russian Research Institute of Viticulture and Winemaking (Demetra × Muscat Summer), submitted for state variety testing in 2016. It ripens in the mid-season: 125–140 days — in the second or third ten days of September. The cluster is large or very large, cylindrical, of medium density or loose, over 35 cm long, usually about 900 g, some clusters twice as big. The berries are very large, about 9 g, elongated-oval, light yellow-green, amber with brown specks in the sun. The flesh is fleshy, delicate and melts in the mouth; the taste is very pleasant, reminiscent of Central Asian varieties, with a light unstable Muscat. Sugar content about 18%, acidity increased (7 g/dm³). The berry has 1–3 seeds.

The bush is vigorous, the flower is hermaphroditic, and the crop must be regulated. The clusters are transportable. The variety is affected by downy mildew at 2.5–3 points and by powdery mildew at 3.5–4 (mainly the clusters), and is resistant to gray mold. It withstands down to −24 °C; in warm regions it is grown without cover, in colder ones it is better to cover the vine.
