LG5582 — high-yielding mid-early sunflower hybrid, distinguished by high drought resistance and adaptability to various soil-climate conditions. Plants reach an average height of about 155 cm, and the 1000-seed mass is 72 grams, indicating the hybrid's large-seeded nature. The seed head is flat with a diameter of approximately 15.8 cm, which contributes to effective yield formation. The vegetative period lasts from 106 to 115 days, enabling the hybrid to be successfully grown in various natural zones of Ukraine, especially recommended for southern regions of the country.
The LG5582 hybrid possesses genetic resistance to seven races of downy mildew (A, B, C, D, E, F, G), as well as to false powdery mildew and major diseases such as root and head rot, frogeye leaf spot, black mold, and dry rot, significantly reducing the risk of yield loss. Drought resistance is rated high (9 out of 10), making this hybrid a reliable choice under insufficient moisture conditions. Additionally, the plant is resistant to cold and lodging, which enhances yield stability.
The potential yield of LG5582 reaches 50 centners per hectare, while actual yields in various regions of Ukraine typically range from 28 to 32 centners per hectare, and up to 4.5 tons per hectare under favorable conditions. The oil content of the seeds is approximately 50%, ensuring high oil production efficiency. The recommended planting density varies depending on soil moisture: up to 55,000 plants per hectare in adequately moist zones and 45-50,000 in dry zones. The cultivation technology is conventional, making the hybrid accessible and convenient for farmers.
