Sunflower PR64F50

Sunflower PR64F50 is a high-yielding mid-early hybrid with linoleic seed type, intended for cultivation in steppe and forest-steppe zones. Plants of this hybrid are tall, with a vegetation period ranging from 106 to 115 days, ensuring full seed head maturation approximately 41-43 days after flowering. Seeds have high oil content, reaching 50%, making this hybrid attractive for oilseed production.

Hybrid PR64F50 exhibits high resistance to major sunflower diseases, including phomopsis, white mold (both head and stem forms), as well as to five strains of downy mildew (A-E). Additionally, the plant demonstrates excellent drought tolerance and lodging resistance, enabling successful cultivation under various climatic conditions, including areas with insufficient moisture. High resistance to root diseases contributes to stable yields and reduced losses.

Recommended planting density varies depending on regional moisture levels: in well-watered zones, optimal density is 55-60 thousand plants per hectare, while in dry regions — 50-55 thousand plants per hectare. Yield potential of the hybrid reaches 45-48 centners per hectare, with actual yields ranging from 30-40 centners per hectare, confirming its high productivity and adaptability. Cultivation technology is traditional, facilitating easy integration into existing agronomic systems.
