General Characteristics
Krasnostop anapsky is a red wine grape cultivar of late ripening period. During the research of varietal breeding populations, the validity in production of the cultivar Krasnostop anapsky with obvious changes in microsatellite sequences as a clone of the famous indigenous Don cultivar Krasnostop Zolotovskii was confirmed. The clone was selected in 1953 by prominent agrotechnologist Zotkin Ivan Ivanovich, submitted to state testing in 2007 in the GSK RF system, and zoned in the North Caucasus region (region No. 6) in 2014. The grape cultivar Krasnostop anapsky received Patent No. 3727 and was entered into the State Register in 2007.
The duration of the vegetative period from the beginning of berry ripening to full physiological maturity is 159 days with a sum of active temperatures of 3090 ºC. Technical maturity occurs at the end of September. In comparison with the cultivar Krasnostop Zolotovskii, Krasnostop anapsky is characterized by a larger cluster and higher productivity. The average yield is 90–120 c/ha (110 c/ha in individual studies). Clusters are medium (100–130 g), berries are small or medium, round, dark blue. The pulp is juicy, sugar content is 20–22 g/100 cm³, acidity is 9–12 g/dm³.
Morphological Description of the Grape Cultivar Krasnostop anapsky
- Shoot: Shoot growth is medium. The number of clusters per developed shoot is 1.1, per fruiting shoot is 1.2. The fruiting coefficient is 1.2. The percentage of fruiting shoots is 95.
- Leaf: The leaf is medium, round, three- or five-lobed, medium-dissected, less frequently deeply-dissected. The leaf blade has raised lower lobes. The upper surface is slightly shiny, varying from smooth to finely blistered.
- Leaf pubescence: The lower surface has dense, bristly-araneose pubescence.
- Leaf incisions: Upper incisions are medium, open, lyre-shaped or closed, with an ovate lumen. Lower incisions are small, open, in the form of an incoming angle.
- Petiolar sinus: The petiolar sinus is open, lyre-shaped, with a rounded base, less frequently almost closed with an oval lumen.
- Teeth: Teeth at the ends of the lobes are wide-angled (wide-triangular) with convex sides. Along the edge of the leaf blade there are small, triangular-serrate teeth, sometimes dome-shaped.
- Flower: The flower type is hermaphrodite.
- Cluster and berry: Clusters are cylindro-conical, of medium density or dense. Berries are round, dark blue. The pulp is juicy. The skin is of medium durability.
Agricultural Technical Features
Winter hardiness is increased. Bud death after wintering does not exceed 25%. The resistance of the grape cultivar Krasnostop anapsky to diseases and pests is at the level of most Vitis vinifera L. cultivars. It prefers chernozem, sufficiently moistened soils. The recommended rootstock is Berlandieri x Riparia Kober 5BB. The recommended training system is high-stem, cordon, with free positioning of shoots.
Winemaking and Product Characteristics
The grape cultivar Krasnostop anapsky has high potential and great prospects for use in winemaking. It is used for the preparation of high-quality table and liqueur red wines. The studied wine materials had the following parameters: alcohol — 12.2% vol., titratable acidity — 6.22 g/dm³, volatile acids — 0.81 g/dm³, reduced extract — 24.6 g/dm³, pH — 3.5. It possesses a large capacity of coloring, extractive, and phenolic substances.
The mass concentration of phenolic substances and their monomeric forms is higher than that of the control Cabernet Sauvignon: the total sum of phenolic substances is 2531.1 mg/dm³, monomeric forms — 1320.5 mg/dm³, polymeric forms — 1210.6 mg/dm³. The amount of anthocyanins is 795.1 mg/dm³. The wine tasting score of table wine materials is 8.73 points, liqueur wines — 9.6 points. Varietal liqueur wines have an intensive coloration, pleasant aroma, currant tone, and soft harmonious taste. According to organoleptic properties, the samples of wine materials show good indicators and high adaptive potential.
