JALON F1

French genetics for high-performance farming

Jalon F1 is a notable three-way hybrid from Euralis Semences that has established itself as a reliable tool for weed and broomrape control. Developed under the guidance of originator Y.-M. Campion, this sunflower embodies the European approach to agronomic efficiency: it was specifically engineered for the Clearfield (Euro-Lightning) system, allowing growers to manage weed pressure with precision during the growth cycle.

Agronomic resilience and yield

In intensive farming environments where pathogens represent a significant risk, Jalon F1 exhibits strong tolerance to a complex of sunflower diseases. Its genetic architecture provides effective resistance against sclerotinia, phomopsis, and phoma, minimizing crop losses under challenging phytosanitary conditions. With a plant height of 160–170 cm, the hybrid is well-suited for mechanical harvesting, while the consistently high oil content (50–55%) makes it a profitable asset for oilseed producers.

Key performance indicators

• Vegetation period: 100–110 days, allowing for flexible harvest planning.
• Technology: full resistance to imidazolinone herbicides.
• Origin: premium French breeding by Euralis Semences, ensuring predictable performance.

Jalon F1 is an balanced solution for growers who prioritize predictability, high oil output, and weed-free fields without the need for manual or mechanical cultivation between rows.
