Onion GULDEN

Technical Profile of 'Gulden' Chive Variety

Developed by the Russian Research Institute of Vegetable Breeding and Seed Production (VNIISSOK), this variety represents a benchmark for intensive salad onion production. The technical value of 'Gulden' lies in the high adaptability of this perennial crop, allowing for efficient, continuous production of greens in open-field conditions.

Production Specifications

• Biological Potential: The variety exhibits exceptional yield for chives, exceeding 100 tons per hectare. This is achieved through intense tillering and a high rate of leaf mass regeneration after harvesting.
• Maturity: The vegetation period to commercial ripeness is less than 90 days, making it an optimal candidate for staggered sowing schedules.
• Phytosanitary Resilience: Genetic resistance to downy mildew (peronosporosis) is a critical technical advantage. In high-humidity conditions, where other varieties require mandatory fungicide applications, 'Gulden' maintains its commercial-grade leaf quality without degradation. This significantly reduces production costs by minimizing pesticide input.

Agronomy and Application

The variety is tailored for the fresh market (salad use), characterized by tender leaves with minimal pungency and high juiciness. Given the morphological traits of chives, manual harvesting is the primary method, ensuring the integrity of the leaf structure and a premium market appearance. Resistance to key pathogens allows 'Gulden' to be integrated into ecologically oriented farming systems, effectively reducing the chemical footprint on the final produce.
