Sunflower SB PRF 10

Genetic Protection and Productivity of SB PRF 10

The selection work of NPO Sunbrid in the SB PRF 10 model focuses on two fundamental tasks: stable oil accumulation under stress conditions and blocking pathogens during early development stages. The plant height of 160–170 cm allows for the efficient use of soil moisture from deeper horizons while ensuring uniform head maturation.

Phytosanitary Potential

The resistance engineering of this hybrid is oriented toward countering the most aggressive infections typical of intensive farming regions:

• Complex Immunity: Genetically programmed protection against phomopsis, phoma, alternaria, and powdery mildew reduces the need for additional fungicide treatments, optimizing costs per hectare.
• Biological Barrier: High resistance to rust and downy mildew ensures the preservation of the leaf apparatus until full physiological maturity, which is critical for proper grain filling.
• Pest Protection: Resistance to the sunflower moth minimizes harvest losses associated with head damage.

Agronomic Parameters

A vegetation period of 100–110 days classifies the SB PRF 10 as a medium-early hybrid, suitable for regions with moderate summers. Within this timeframe, the plant manages to accumulate 45–50% oil content, maintaining seed quality even during moisture deficits in the second half of the summer. The sturdy stalk prevents lodging, facilitating mechanical harvesting with minimal losses at the cutting edge.
