Onion Rosario

Technical Profile: Chives "Rosario"

"Rosario" represents a precise selection achievement in the perennial chives segment, developed by specialists at the Federal Research Center for Vegetable Growing. The technical value of this variety lies in the specific dynamics of biomass accumulation and the biological resilience incorporated by the originators (Agafonov A.F. et al.).

Morphology and Vegetative Cycle

The key parameter of this variety is an optimized maturation cycle, which completes within 90 days. Unlike wild-type counterparts, "Rosario" exhibits a distinct salad-grade profile. The selection engineers focused on maximizing the mass of both the foliage and the bulb: the claimed weight for the marketable portion is 170–180 grams. This figure significantly exceeds the average values for this species, positioning the variety as an efficient tool for commercial vegetable production.

Operational Characteristics

• Perennial Crop: A high regeneration rate allows for multiple harvests across several seasons without compromising the quality of the marketable product.
• Culinary Profile: The salad-grade classification ensures an ideal balance of mild pungency and high essential oil content, which is critical for market demand.
• Production Potential: The consistency of traits, confirmed by the patent holders, guarantees predictable performance when standard agricultural practices are followed.

The practical application of "Rosario" is justified in intensive farming systems where early, nutrient-dense production with high marketable biomass density is required. The stability of the genetic material, legally protected by patent, minimizes the risks of crop degradation, ensuring uniform maturation across the entire field.
