The Ortega 7+ Sumo sunflower hybrid is a high-yielding, intensive-type crop developed by the Serbian Institute of Agriculture and Vegetable Growing NS Seme (Novi Sad). It features a medium-early maturity period with a vegetative cycle of 108-113 days and plant height of 165-175 cm. Its yield potential reaches 57 centners per hectare, with oil content in seeds of 51-53%, making it an attractive option for high-quality oil production.
Ortega 7+ Sumo has a strong root system and high resistance to adverse soil-climatic conditions, including drought and cold. Its drought resistance is rated at 9 points, and cold resistance at 8 points. The hybrid also demonstrates high tolerance to a broad spectrum of sunflower diseases, including fomopsis, anthracnose, white mold, downy mildew, rust, gray mold, septoria, fomosis, and alternaria, with resistance ratings of 8 to 9 points. Special attention has been given to resistance to bird cherry — the hybrid is resistant to 7+ races of this parasitic plant, allowing cultivation in areas where this pest is prevalent.
The Ortega 7+ Sumo hybrid is recommended for cultivation in southern, eastern, and central regions using the Granstar (Sumo, Express) technology. The recommended seeding density before harvest is 55,000–60,000 plants per hectare under adequate moisture conditions and 45,000–50,000 plants per hectare in drought conditions. Thanks to its combination of high yield, disease resistance, and adaptability to various cultivation conditions, this hybrid is a reliable choice for efficient and stable sunflower production.
