Antonina

Technical Profile of the "Antonina" Hybrid

The "Antonina" variety, developed by the A.K. Chaika Federal Research Center for Agrobiotechnologies of the Far East, is a specialized damson plum (Prunus insititia) hybrid. Its primary genetic goal was to bridge the gap between extreme climatic resilience and high-end dessert fruit quality.

Agronomic Performance and Hardiness

The core technological strength of "Antonina" lies in its exceptional cold hardiness, reliably withstanding temperatures down to -30°C. With a medium maturity cycle of 86–100 days from flowering, the plant effectively completes its vegetative development in short-season regions. Yields range from 35 to 50 kg per mature tree, driven by a dense, stable fruit-bearing structure that responds well to standard orchard management practices.

Morphological and Organoleptic Data

The fruit architecture of "Antonina" displays significant potential for marketability:

• Fruit weight: 36–50 g, considered large for this specific hybrid category.
• Shape: Uniformly round.
• Skin color: Vibrant yellow.
• Texture: Succulent, juicy pulp with a high-quality mouthfeel.
• Taste profile: Dessert-grade with sugar content exceeding 14%.

Application and Market Utility

The high sugar concentration and juicy consistency make "Antonina" a versatile asset for commercial growers. While the variety is highly valued for the fresh produce market, its specific biochemical profile makes it an excellent candidate for food processing, including the production of high-quality spirits, liqueurs, and traditional slivovitz. Its structural integrity ensures good transportability, maintaining high quality throughout the supply chain.
