Hybrid sunflower PR64F66 (Pioneer F66) is a medium-early, high-yielding linoleic-type variety intended for cultivation in various climatic regions of Ukraine, including dry southern zones, forest-steppe, and steppe. The vegetation period is 110-115 days, ensuring uniform maturity and high variety purity. Medium-height plants with convex heads exhibit good lodging resistance, which helps preserve yield and facilitates harvesting.

One of the key features of hybrid PR64F66 is its high tolerance to 7 races of downy mildew (A-G), making it an optimal choice for fields affected by this disease. Additionally, the hybrid shows resistance to diseases such as fusarium, fusarium wilt, and false powdery mildew, with resistance ratings at level 7. The hybrid also exhibits high drought tolerance (rating 9), enabling successful cultivation under water-deficient conditions.

Sunflower seeds of PR64F66 are characterized by high oil content — approximately 50% — ensuring high-quality oil production. The potential yield reaches 55 centners per hectare, with recommended planting density varying depending on the moisture zone: 55-60 thousand plants per hectare in well-watered zones and 50-55 thousand plants per hectare in dry regions. Seeds are packed at 150,000 per bag, which is convenient for farmers and promotes efficient planting.
