Stinger SU sunflower is a mid-early linear hybrid of intensive type with high genetic resistance and yield potential. Plant height varies between 175–185 cm depending on moisture level, ensuring optimal conditions for yield formation. The hybrid exhibits high initial growth energy in early organogenesis stages, promoting rapid development and strengthening of plants. The vegetation period lasts approximately 116–120 days, allowing effective use in various climatic zones.
Stinger SU features high oil content, reaching up to 55%, making it attractive for oilseed production. The hybrid shows high resistance to major sunflower diseases, including false powdery mildew, phomopsis, phomosis, as well as stem and head sclerotinia. Additionally, it demonstrates resistance to stem wilting and tolerance to various races of the thistle aphid (A-G), ensuring stable yields even under adverse conditions. Overall disease tolerance is rated at 8 out of 10, and yield stability at 9 out of 10.
Recommended cultivation zones include Northern Steppe, Forest-Steppe, and Polесье, where the hybrid performs best. Optimal plant density at harvest depends on moisture level: 55–60 thousand plants per hectare under adequate moisture, 45–55 thousand under unstable conditions, and 40–45 thousand under insufficient moisture. Thanks to its combination of high oil content, disease resistance, and adaptability to various climatic conditions, Stinger SU is an advantageous choice for intensive and stable sunflower production.
