The OBS makes every effort to improve the quality of these products
- Quality safety : each seed lot is subject to controls to ensure its quality and compliance.
- Evaluation security : before they are marketed, the OBS submits all its varieties to the regional experimentation network organised by the producers.
- Security of supply : our commitment: to meet 100% the demand for our seeds.
