SF 270

SF 270 is a sunflower (Helianthus annuus L.) hybrid of the mid-maturing type, intended for cultivation in the Central Chernozem region of Russia, particularly in the Lipetsk region. The vegetation period is about 123 days, during which the plant reaches average height and does not form branches. Leaves have green coloration with blistering ranging from weak to medium, while ray florets are yellow. Seeds are characterized by a mass of about 51.2 g for 1000 units, weakly expressed marginal stripes, and the absence or very weak expression of stripes between the edges. The average yield of the hybrid in the region is 29.0 c/ha, with a maximum of up to 41.9 c/ha, while oil content in seeds reaches 48.5–56%, ensuring a high oil harvest of about 12.1 c/ha. The SF 270 hybrid is distinguished by high resistance to diseases, including downy mildew and downy mildew A-G+, making it a reliable choice for farmers seeking to minimize crop losses. It is moderately susceptible to white mold. To achieve optimal productivity, it is recommended to follow sowing rates of 60-65 thousand plants per hectare, avoiding excessive thickening of plantings. The hybrid shows high initial growth energy and possesses endurance to unfavorable conditions such as cold and drought, expanding possibilities for its cultivation in various climatic zones. SF 270 is a classic mid-maturing sunflower hybrid that combines high yield, quality seed characteristics, and resistance to major diseases. It is recommended for cultivation in the Central Chernozem region of Russia, where it shows stable results. Due to its characteristics, this hybrid is suitable for producing high-quality oil and ensures efficient use of land resources.
