Sunflower SU RF 1 SP

Genetic Potential and Oil Content

Serbian breeding from the Institut Za Ratarstvo I Povrtarstvo traditionally focuses on the balance between early maturity and the accumulation of organic compounds. The SU RF 1 SP sunflower hybrid demonstrates oil content in the 50-55% range, which is a high indicator for a short-vegetation hybrid. This is achieved through intensive metabolism during the seed-filling period, which is critical under moisture-deficient conditions.

Phytosanitary Barrier

The technical resistance of the hybrid to pathogens is based on built-in protection factors that minimize the risk of epiphytotics. The agronomic value of SU RF 1 SP lies in its complex immunity against three of the most dangerous diseases:

• Verticillium wilt: suppression of pathogen development within the plant's vascular system.
• Sclerotinia: limitation of mycelial growth in the stalk and seed head.
• Phomopsis: reduced probability of leaf damage and stalk necrosis.

These characteristics allow for reduced pesticide reliance, cutting down the number of fungicide applications per season.

Morphology and Vegetation

The 90-100 day maturation period classifies SU RF 1 SP as an early-maturing hybrid. This allows for the effective use of early-season moisture and helps avoid the summer heat stress that often suppresses late-maturing crops. The medium-sized, black-coated seeds exhibit high germination energy, ensuring uniform emergence even at lower initial soil temperatures. Choosing this hybrid is a prudent strategy for farms practicing intensive crop rotation and aiming for stable yields in regions with short frost-free periods.
