ED 155

Technical Profile of ED 155 Sunflower

The ED 155 sunflower hybrid is the result of focused breeding efforts by the V.S. Pustovoit All-Russian Research Institute of Oil Crops (VNIIMK) and the Elite Dona Agro-Industrial Firm. The hybrid’s genetic architecture is optimized for yield stability under diverse agricultural conditions.

Vegetation Cycle and Phytosanitary Resilience

The vegetation period spans 110–120 days. This duration is engineered to balance biomass accumulation with uniform seed maturation, avoiding the late-season risks associated with excessive rainfall. The hybrid provides robust protection mechanisms against critical pathogens:

• Peronospora (Downy Mildew): Built-in resistance markers significantly reduce crop loss risk in high-humidity environments, protecting the root system during early development.
• Powdery Mildew: The genetic defense mechanisms prevent mycelial colonization of the leaf surface, ensuring that the plant maintains maximum photosynthetic efficiency throughout the grain-filling stage.

Agronomic Advantages

The integration of Russian breeding expertise from the VNIIMK institute results in superior field emergence and consistent growth vigor. By reducing the reliance on aggressive fungicide programs to manage Downy Mildew and Powdery Mildew, farmers can effectively lower their total cost of production. ED 155 serves as a reliable solution for commercial fields where output predictability is prioritized through standardized sowing and crop management practices.
