Sugar beet Courlis

French Breeding for High Sugar Content

The sugar beet variety 'Kurlis' from the French breeding company Florimond-Desprez Veuve et Fils is a benchmark for how European adaptation technologies perform in fields with complex phytosanitary profiles. This hybrid was developed with a focus on yield stability under intensive farming conditions, where the risk of foliar diseases is a constant concern.

A Biological Shield Against Pathogens

The key feature of 'Kurlis' lies in its comprehensive resistance. Agronomists choosing this hybrid gain a strategic advantage against the most dangerous threats:

• Phytopathogenic complex: High resistance to root rot (Rhizoctonia) and downy mildew reduces the need for excessive early-season treatments.
• Foliar disease protection: The hybrid demonstrates solid resistance to Cercospora leaf spot and powdery mildew, maintaining a green leaf canopy right up until harvest.
• Root health: Florimond-Desprez genetics provide robust protection against storage rots, which is critical for long-term storage after harvest.

Morphology and Economic Returns

The cylindrical-conical shape of the 'Kurlis' root allows for excellent penetration into the soil, forming a quality structure without excessive deep-rooting. The medium size of the root, combined with high planting density, ensures stable tonnage. However, the primary argument for this hybrid is its sugar content. A level of 21–22% places 'Kurlis' firmly in the premium segment for processing plants focused on high refined sugar extraction rates. In the temperate climate of France and similar regions, this hybrid justifies its seed costs by minimizing storage losses and maintaining high sugar levels, making it a preferred choice for professional agricultural enterprises.
