Sunflower WEIDELEVSKY

Technical Profile of the "Veydelevskiy" Hybrid

The breeding work conducted by the VNIIMK and the Veydelevskiy Research Institute has resulted in a crop material optimized for stable oilseed production. The primary value of the "Veydelevskiy" hybrid lies in its combination of biological defense barriers and efficient oil accumulation rates, which define its overall economic performance.

Phytopathological Resistance as a Core Defense Strategy

The engineers behind this hybrid focused on minimizing the need for heavy fungicide applications. Its genetic resilience is built upon proven resistance to a complex of major pathogens:

• Downy Mildew (Peronosporosis): prevents premature crop death under high-humidity conditions.
• Phomopsis and Phoma: ensure stem integrity and proper nutrient flow to the head during the grain-filling stage.
• Sunflower Moth: significantly reduces losses from this pest, which is critical for preserving seed quality and marketability.

Oil Content and Vegetation Dynamics

A growing period of 110–120 days places "Veydelevskiy" in the mid-season maturity group. This provides an ideal window for northern and central cultivation zones, allowing the crop to complete its biological cycle before the onset of critical autumn cooling. An oil content of 45–50% confirms strong processing potential. The characteristic black seed color indicates a robust, dense hull that protects the kernel from environmental stressors in the field.

Practical Conclusion

This hybrid is a targeted solution for farming operations that prioritize a balance between crop protection against prevalent fungal infections and consistently high oil yields using standard agronomic practices.
