Common sunflower TUNCA

Stable yields with minimal risks

Choosing the Limagrain Tunka hybrid is a strategic move for farms focused on predictable results, even under high disease pressure. French breeding serves as a precise tool for loss mitigation: thanks to a robust genetic resistance complex, this sunflower confidently withstands challenges in areas with high pathogen concentration.

Pathogen defense as a key advantage

Field practice proves that Tunka is indispensable in fields with intensive crop rotation where soilborne infections have accumulated. The hybrid demonstrates high resistance to a complex of rots (head rot, root rot, charcoal rot) and effectively counters Phoma and Phomopsis. A significant bonus for agronomists is its high tolerance to sunflower broomrape, allowing the use of fields infested with aggressive parasite races.

Field Performance and Agronomy

• Vegetation period: 110–120 days. This "golden mean" allows for comfortable planning of the harvesting campaign, avoiding delays during autumn rains.
• Morphology: The plant reaches 140–150 cm in height. This stature simplifies header operation and minimizes harvesting losses.
• Oil content: A level of 45–50% makes the product highly attractive to processors, ensuring high-quality grades upon delivery.

Tunka unlocks its full potential in the field when basic technological standards are met. The medium-sized head is optimally balanced, facilitating uniform seed filling. For farms operating in high-risk zones for downy mildew, this hybrid acts as a reliable shield, helping to reduce the need for costly fungicide applications during critical growth stages.
