Sunflower Heliamax

Stable yields with intensive protection

French selection from R2N offers a solution for farmers facing field weed pressure and fungal diseases. The 'Heliamax' sunflower hybrid is designed for those prioritizing the 'Clearfield' production system using imidazolinone herbicides. The compatibility with Euro-Lightning allows for effective weed control throughout the growing season without compromising crop development.

Biological potential and field characteristics

In commercial field conditions, the hybrid reaches a height of 160–170 cm. This is an optimal height, facilitating harvesting with standard headers and minimizing lodging risks during adverse weather. The selection focus was placed on immunity against soil-borne and leaf infections:

• High tolerance to Verticillium wilt and Phomopsis.
• Strong protective barrier against various rots and powdery mildew.
• Genetic resistance to Downy mildew and charcoal rot, which is crucial when crop rotation is interrupted.

Economic value

The key commercial advantage of 'Heliamax' is its oil content of 50–55%. For a farm, this translates to higher market demand and better profitability per ton. By choosing this hybrid, the agronomist secures a balanced product: crop protection is guaranteed by herbicide technology, and yield reliability is backed by the strong phytosanitary immunity of French R2N breeding.
