Onion OSTRYAK

Engineering Features of the «Ostryak» Onion

The breeding work of the «Heterozisnaya Selektsiya» company during the development of the «Ostryak» variety focused on achieving a balance between the density of the outer scales and the shelf life of the bulbs. Unlike early-maturing varieties, which often have a loose neck structure, «Ostryak» demonstrates pronounced resistance to rot during prolonged storage.

Technical Bulb Profile

• Protective Layer: The dark bronze and bright brown coloration of the scales is due to a high content of anthocyanins and flavonoids. This is not merely a decorative trait but a robust barrier against mechanical damage and pathogen penetration during storage.
• Storage Potential: The unique genetic potential ensures the preservation of marketability and structural integrity for 9–10 months. The stability of cell walls minimizes dry matter loss, which is critical for commercial onions intended for spring distribution.
• Adaptability: Developed with the participation of originators «Heterozisnaya Selektsiya», «Vashe Khozyaistvo», and «Agrofirma Mars», the variety has passed rigorous selection testing for stress resistance, making it a reliable choice for intensive vegetable production.

Choosing this hybrid is a sound decision for farms targeting long-term storage without significant losses. The dense structure of the bulb reduces the risk of injury during mechanized harvesting, while the precise chemical composition ensures the maintenance of flavor profiles well into the following season.
