VISA

Technical Profile of Winter Wheat 'Viza'

The 'Viza' variety, developed by the P.P. Lukyanenko National Grain Center, is a soft winter wheat cultivar optimized for stable production in temperate and high-risk climatic zones. The breeding focus centers on integrated biological resilience, ensuring predictable performance under varying environmental pressures.

Phytosanitary Resilience

The core technical value of this variety lies in its robust genetic resistance to primary leaf and stem pathogens. 'Viza' demonstrates effective control against major agricultural threats, including:

• Mycosphaerella leaf blotch (Septoria);
• Leaf rust and other rust species;
• Fusarium head blight, which is crucial for maintaining commercial grain quality under high humidity during the ripening stage.

These characteristics allow farmers to optimize fungicide application schedules, reducing chemical load without sacrificing yield potential.

Agronomic Specifications

The variety features a balanced morphology designed to minimize harvest losses. Its high resistance to lodging, supported by strong straw architecture, makes it well-suited for intensive cultivation practices, including the application of high nitrogen fertilizer rates.

With a thousand-kernel weight (TKW) ranging from 35 to 50 grams, growers have the flexibility to adjust seeding rates based on soil moisture and planting windows. A vegetation period ranging between 220 and 270 days allows the crop to effectively utilize active temperatures, ensuring consistent grain filling across different regional zones.
