Sunflower Oleean

French breeding for stable yields

The «Ollean» sunflower hybrid by R2N is a result of years of research in French laboratories, aimed at creating high-yielding plant material for intensive farming. This hybrid has secured a solid position in the medium-early maturity segment, where the balance between ripening speed and oil accumulation is crucial.

Agronomic potential and plant protection

The main strength of the Ollean hybrid is its comprehensive immunity. In high-humidity conditions and environments with high pathogen pressure, this hybrid shows exceptional resistance to a wide range of diseases:

• Alternaria, Verticillium wilt, and Sclerotinia;
• Phomopsis, Phoma, and Powdery mildew;
• High tolerance to Downy mildew.

Furthermore, R2N breeders have focused on genetic resistance to the sunflower moth, which significantly reduces yield losses during the head-ripening stage. With proper field management, plant height ranges from 150 to 180 cm, allowing the hybrid to effectively utilize soil nutrients without excessive lodging risks.

Economic indicators

With a vegetation period of 90–110 days, Ollean is an optimal choice for farms managing crop rotations with tight harvest windows. An oil content of 45–50% makes this hybrid highly attractive to processors seeking high-quality sunflower output. The stability of these metrics across various climatic zones reinforces R2N’s reputation as a developer of premium European-grade genetics.
