DR 17

Genetic Profile and Adaptability

The sunflower hybrid "DR 17," developed by breeder Nikolai Savelyevich Cheban, is engineered for agricultural environments where pathogen pressure requires superior plant immunity. The technical design of this hybrid focuses on maximizing yield potential by minimizing the impact of fungal diseases that commonly thrive in fluctuating climatic conditions.

Disease Resistance Mechanism

The core technical advantage of "DR 17" lies in its robust genetic resistance to rust and powdery mildew. By effectively blocking mycelial development, the hybrid reduces the need for frequent chemical fungicide applications. Preserving the leaf surface area throughout the vegetation period is crucial for photosynthetic efficiency and ensures optimal grain filling, which is fundamental to the hybrid's overall productivity.

Oil Content and Yield Metrics

With an oil content ranging from 50% to 55%, "DR 17" offers significant value for industrial processing. This high lipid concentration is achieved through optimized metabolic pathways during the grain-filling stage, allowing the plant to synthesize fatty acids efficiently even under moderate stress. For producers, this translates into a higher quality harvest and improved economic efficiency at the extraction stage.
