Alonso F1 (BGS 234)

Reliability and yield potential of Alonso F1

Bejo’s Dutch breeding program continues to set the standard in the long-day onion segment. The Alonso F1 (BGS 234) hybrid is a solution for growers focused on high-tech processing and long-term storage. Unlike many standard varieties, this hybrid combines aggressive resistance to key pathogens with superior marketability.

Disease resistance and agronomics

The main advantage of Alonso F1 is its robust immune system. In high-humidity conditions with significant infection pressure, the plant demonstrates high tolerance to downy mildew and Fusarium wilt. This effectively lowers fungicide application costs, allowing farmers to focus on nutrient management. Importantly, the hybrid is highly effective against pink rot, which is often a limiting factor in infested soil.

Designed for processing

The visual profile of Alonso F1 meets the strictest market demands:

• Perfectly round bulb shape, optimized for mechanical peeling and slicing.
• Dense, dark-bronze scales that ensure excellent shelf life.
• Pure white flesh that maintains its quality even after long-distance transport or extended storage.

This onion is primarily targeted at the processing industry. Its dense structure and uniformity ensure a significantly higher processed product output compared to market equivalents. High growth intensity under long-day conditions guarantees a marketable yield even in regions with shorter growing seasons.

Who is this hybrid for?

Alonso F1 is a professional-grade choice. It is not intended for hobby gardens, as it is specifically engineered for large-scale operations, mechanized harvesting, and industrial processing. If your goal is to secure a uniform crop that remains stable through months of storage, this Bejo hybrid will prove its value from the very first harvest.
