BISON

Genetic Architecture for Yield Stability

The «Bizon» hybrid, developed by the Belgian breeder Sesvanderhave Nv/Sa, is an engineered solution for intensive sugar beet production. It balances high sugar content (19-20%) with a robust defensive profile, designed to maintain physiological efficiency even under intense pathogen pressure.

Phytopathological Defense Mechanisms

The hybrid’s resistance to sugar beet nematode (Heterodera schachtii) is based on specific tolerance genes that inhibit the parasite’s lifecycle within the root system. By preventing early-stage nematode damage, the plant avoids subsequent secondary infections, ensuring better root integrity and sugar accumulation.

• Foliar Disease Resistance: The genetic profile of «Bizon» is specifically tuned for high resistance to Cercospora leaf spot, Ramularia leaf spot, and powdery mildew. This reduces the dependency on frequent fungicidal applications, streamlining agronomic management.
• Rhizomania Control: Equipped with the Rz1 resistance gene, «Bizon» effectively suppresses the rhizomania virus. This allows the crop to maintain essential vascular function throughout the entire growing season, which is crucial in fields with a history of viral presence.

Technically, «Bizon» is optimized for high-risk soil conditions. Its ability to maintain growth velocity under moisture stress, combined with an immune-like response to major fungal and viral threats, makes it a reliable asset for maximizing sugar yields per hectare. The synergy between high sugar concentration and field resilience positions this hybrid as a top-tier choice for industrial-scale sugar production.
