Sunflower PR64A15 is a medium-early simple hybrid of linoleic type with high productivity potential. Plants have medium height and straight stems, which are characterized by strength and resistance to lodging. The head of this hybrid is semi-downward, medium-sized, convex, and well-covered with seeds, which have an elongated shape, facilitating sowing with pneumatic seeders. The 1000-seed mass is 60-64 grams, and the oil content reaches 50%, which is a very high indicator for this type of sunflower. Hybrid PR64A15 exhibits high resistance to broomrape (Orobanche cumana) race A-E, significantly reducing the risk of yield losses. Moreover, it has excellent drought resistance and heat tolerance, making it particularly suitable for cultivation in Steppe and Forest-Steppe regions. The high self-pollination rate contributes to increased yield even in areas with limited insect pollinators. The dark green stem and leaf cover ensure good plant development and resistance to lodging and seed shattering. Sunflower PR64A15 is recommended for cultivation in regions with variable climatic conditions, where resistance to stress and pests is crucial. Its morphophysiological characteristics, such as medium stem height, abundant leaf cover, and well-formed head, ensure stable and high yield. High oil content makes this hybrid attractive for producing high-quality sunflower oil, and its adaptability to various cultivation conditions facilitates broad application in the agricultural sector.
