Main Characteristics
The Odessky Ranny grape variety was bred in 1946 at the V. Ye. Tairov Ukrainian Research Institute of Viticulture and Winemaking by breeders Ye. S. Komarova, M. P. Tsebry, P. K. Aivazian, A. N. Kostyuk, and Ye. N. Dokuchaeva by crossing the Chaush and Muscat Hamburg varieties. In Ukraine, the variety has been regionally zoned since 1973 in the Kirovohrad region.
Odessky Ranny is a table grape variety of a very early ripening period used for fresh consumption and juice production. From bud break to harvest maturity of the berries in Odesa, it takes 110–112 days at a sum of active temperatures of 2300–2400 °C; harvest maturity occurs on August 12–20. The average cluster weight is 303 g, and the average weight of 100 berries is 310 g. The mechanical composition of the cluster is characterized by the following indicators: juice — 83.7%, skin and dense parts of the pulp — 11.4%, stems — 3.2%, and seeds — 1.7%. The sugar content of the berry juice at harvest reaches 15.7 g/100 ml with an acidity of 4.5–8.1 g/l. The taste of the berries is harmonious with a muscat aroma, and the tasting score of fresh grapes is 7.5–7.8 points. Marketability of the clusters reaches 60–70%. The variety is insufficiently transportable, withstanding a berry detachment force of 240 g and a crushing force of 780–800 g.
Morphological Description of the Odessky Ranny Grape Variety
The leading characteristics of the Odessky Ranny variety are leaves with characteristic triangular lateral sinuses, long wine-red petioles, cylindro-conical compact clusters, light green berries with a muscat flavor, and very early ripening.
- Young shoot (shoot tip): The tip and first young leaves are light green with a pinkish margin, light bronze spots, and dense cobwebby pubescence. Subsequent leaves are light green with a yellowish tint, glabrous on the upper surface and with bristly pubescence on the lower surface.
- One-year-old matured cane: Yellowish-brown, with more intensely colored nodes.
- Mature leaf: Medium-sized, round, five-lobed, deeply divided, wrinkled or finely blistered. Upper and lower lateral sinuses are deep, closed, with a triangular lumen, less often open and lyre-shaped with a narrow mouth. The petiolar sinus is closed with a broadly elliptical lumen. Teeth at the tips of the lobes are acute; marginal teeth are triangular, tall, with a broad base and slightly concave sides. Pubescence on the lower leaf surface is bristly and weak. Autumn leaf coloration is yellow.
- Nursery plants (saplings): Vigorous, semi-spreading, well-foliated, forming numerous lateral shoots.
- Flower: Hermaphroditic (bisexual).
- Cluster: Medium-sized (15–17 cm long, 13–15 cm wide), cylindro-conical, compact or medium-compact, sometimes winged. The peduncle is of medium length — 4–5 cm.
- Berry: Medium-sized (16–18 mm in diameter), round, light green, sometimes with a yellowish tint. The skin is thin; the pulp is juicy. Each berry contains 2–3 small seeds.
Agrotechnical Features and Resistance
Vines of the Odessky Ranny grape variety are vigorous, and one-year-old shoots mature well (85%). The variety is characterized by moderately high but insufficiently stable yields: at the V. Ye. Tairov Ukrainian Research Institute of Viticulture and Winemaking under non-covered cultivation, yields vary from 70 to 130 c/ha and average 90 c/ha, while at the Kirovohrad State Variety Testing Plot for 1966–1971 they reached 125 c/ha. Fruit-bearing shoots account for 60–65%, with an average of 0.6–0.8 inflorescences per developed shoot and 1.2–1.3 per fruit-bearing shoot. Flower drop and berry shot (millerandage) are negligible.
The Odessky Ranny variety is susceptible to gray rot of berries, downy mildew, and powdery mildew (oidium), and is also prone to damage by the European grapevine moth. Its frost resistance is low: vines are damaged when temperatures drop to minus 18 °C, though yields partially recover due to good fruiting on lateral shoots. In the Kirovohrad region, the variety can only be cultivated with winter covering using a multi-arm, low-trunk fan training system and medium pruning leaving 7–8 buds per cane. In warmer regions of the Ukrainian SSR, cordon training on a trunk 70–120 cm high and short pruning to 3–4 buds is possible. The Odessky Ranny grape variety grows well on Riparia × Rupestris 101-14, 3309, Berlandieri × Riparia 5BB, SO4, and Teleki 5C rootstocks.
