Sunflower PR64H91 is a mid-early hybrid with a vegetation period of 117 to 122 days, characterized by high yield and adaptability to various soil-climatic conditions. Plants reach a height of about 160-165 cm, have strong stems and a well-developed root system, ensuring drought resistance and rapid early growth. The hybrid demonstrates high plasticity and responds well to optimal nutrient supply, making it suitable for cultivation in the Steppe and Forest-Steppe regions, especially under hot and dry climates.
One of the key features of PR64H91 is its high oil content in seeds, reaching 48.8%, which ensures an overall oil yield of 1241 kg per hectare. The hybrid also exhibits high oil content and resistance to various diseases, including fusarium and white mold, as well as tolerance to seven strains of downy mildew (A-G). These characteristics make it a reliable choice for producing high-quality sunflower oil with high oleic acid content.
PR64H91 is characterized by stable yield, which, according to state trials, averages 29.9 centners/ha with maximum yields reaching 50.6 centners/ha. The 1000-seed mass is approximately 59 g, and the hybrid takes about 76 days to reach flowering. Due to its combination of high productivity, resistance to stress factors, and quality oil characteristics, this sunflower is recommended for cultivation on various soil types, including sandy and challenging conditions, ensuring stable and high yields.
