Sonest F1

A Benchmark for Short-Day Onion Production

The «Sonesta F1» onion from the Swiss breeding company Syngenta is widely regarded as a market standard in the short-day hybrid segment. Developed for professional vegetable farming, this hybrid addresses the critical need for early, high-quality produce that maintains superior storage capabilities—a rare combination for onions in this maturity group.

Agronomic Profile and Disease Resistance

The core strength of this hybrid lies in its strong genetic resistance to soil-borne pathogens. Syngenta’s breeding efforts have focused on protecting the yield from pink root rot and Fusarium, enabling producers to achieve consistently high yields of 90–100 tons per hectare, even in fields with high disease pressure.

Marketability and Post-Harvest Performance

«Sonesta F1» produces perfectly round, uniform bulbs with bright brown skin and crisp white flesh. With a dry matter content of up to 10%, it is suitable for both the fresh market and processing. However, its primary competitive advantage becomes apparent after harvest: under proper storage conditions, this onion maintains excellent market quality for 8–9 months.

• Type: Bulb onion, short-day.
• Maturity: 110–120 days.
• Yield Potential: 90–100 t/ha.
• Storage: Up to 9 months.

Today, «Sonesta F1» remains one of the most reliable assets for agribusinesses focused on long-cycle sales and strict quality standards.
