TERRIVIN

Technical Profile of the 'Terwin' Onion Hybrid

The 'Terwin' hybrid, developed through a partnership between French and American breeding programs, represents a high-performance solution for industrial vegetable cultivation. Its genetic architecture is specifically optimized for high-density planting and mechanical harvesting.

Performance Indicators

• Maturity Cycle: A 120–130 day growing period ensures consistent results for large-scale operations.
• Yield Potential: Exceeding 100 tonnes per hectare, this hybrid leverages efficient plant architecture to maximize biomass conversion.
• Dry Matter Content: At 13–15%, the high solids content is a critical metric that defines both processing utility and long-term shelf stability.

Physical and Structural Integrity

The flat-round bulb, weighing 90–100 grams, is engineered for uniformity, which is essential for modern grading lines. The bronze-yellow outer skin provides a robust physical barrier, protecting the inner white tissue from mechanical stress during logistics. The bulb's intrinsic quality allows for a storage life of 8–9 months, maintaining marketability and culinary value throughout the off-season.

Business Application

From an agronomical and business standpoint, 'Terwin' offers a dual-purpose strategy. Its characteristics make it suitable for both the fresh market (salad type) and the processing industry. The ability to store produce for up to 9 months allows producers to strategically manage market supply and avoid seasonal price volatility, ensuring higher profitability per unit of area.
