ST 9093

ST 9093 is a sunflower hybrid (Helianthus annuus L.) intended for cultivation in the Central-Black Earth region, specifically recommended for the Tambov region. This mid-early variety is characterized by high seed yield, averaging 31.4–37.8 c/ha, with maximum figures reaching up to 43.6 c/ha under favorable conditions. The plant is of medium height, unbranched, with green leaves of medium size that exhibit medium to strong blistering and serration. The flowers are yellow, with narrow ovate ray florets and tubular disc florets featuring anthocyanin-colored stigmas. The head is semi-inverted, and the seeds are narrow ovate, black, without distinct stripes. ST 9093 sunflower seeds have a high oil content ranging from 47.4% to 50.6%, ensuring a stable and high oil harvest of 10.4–16.5 c/ha. The hybrid's oil content exceeds standard indicators, making it advantageous for oil production. Due to its resistance to diseases and adverse conditions, this hybrid is popular among agronomists and agricultural enterprises. However, it is important to note that the variety is not resistant to downy mildew. The ST 9093 hybrid exhibits moderate resistance to white mold, enhancing its reliability during cultivation. Its classic morphology and stable agronomic characteristics make it a suitable choice for oilseed production in regions with chernozem soils. High oil content and adaptability to regional conditions allow for effective use of this sunflower for obtaining quality raw materials and maximizing yield.
