Karavayivska Yurozhna

Genetic Potential and Productivity

"Karavaivska Urozhaina" is a result of selective breeding by the M.M. Gryshko National Botanical Garden, specifically adapted for the Ukrainian climate. A key technical feature of this cultivar is its high ovary fertility, ensuring stable yields even amid spring temperature fluctuations. Unlike wild genotypes, this variety shows a pronounced tendency toward cluster formation, which significantly streamlines the harvesting process.

Fruit Morphology and Flavor Profile

Technically, the fruit is a multi-seeded berry weighing 5–8 grams. The skin is smooth and thin, allowing for consumption without peeling—a critical factor for commercial viability. The internal structure is characterized by high sugar concentration and balanced acidity, providing a sweet, dessert-quality flavor. The firm flesh offers excellent transportability, a rare trait for actinidia of this size.

Agrotechnical Specifications

• Type: Actinidia arguta cultivar.
• Ripening period: Second half of September.
• Flowering type: Dioecious (requires a male pollinator plant within a 10-15 meter radius).
• Resilience: High winter hardiness typical of NBG Gryshko breeding programs.

The practical value of this cultivar lies in the synergy between high yield and the fruit's suitability for long-term storage under controlled temperatures. The plant requires trellising: due to the vine's vigorous growth, annual crown pruning is necessary to prevent overcrowding and ensure sunlight penetration to internal fruits.
