TSARSKOSELSKY

Technical Profile of 'Tsarskoseльский' Onion

Developed by the Federal Scientific Center for Vegetable Production, the 'Tsarskoseльский' onion is a late-maturing cultivar with a vegetation period spanning 150 to 160 days. This specific biological cycle is designed to maximize bulb density and storage potential.

Morphology and Commodity Standards

• Bulb Architecture: The cultivar exhibits a distinct shape—an intermediate between oblate-cuboidal and flat. This specific geometry optimizes mechanical handling, reduces bruising during sorting, and ensures efficient volume distribution in storage crates.
• Coloration: The bulb features a distinct white skin, positioning it as a premium choice for food processing and culinary applications where aesthetics and flavor mildness are paramount.
• Maturity and Development: With a 150-160 day cycle, the plant invests energy in forming robust, dry outer layers, which serve as a natural barrier against storage pathogens.

Operational Practicality

For large-scale agricultural operations, 'Tsarskoseльский' serves as a stable, long-shelf-life commodity. The late maturation allows for significant dry matter accumulation. Producers should note that the 160-day development window is critical: precise synchronization with the local frost-free season is essential to ensure the bulb reaches full physiological maturity, as premature harvesting will compromise its inherent storage longevity.
