Sunflower A 61 is a high-yielding, simple modified hybrid with high resistance to various strains of downy mildew (A-G+) and a range of diseases, including false powdery mildew, gray and white mold, and rust. This hybrid is tolerant to the herbicide tribenuron-methyl (Granstar) when applied once at a rate of 50 g/ha, enabling effective weed control and increased yield. Its high drought tolerance and adaptation to adverse climatic conditions make A 61 suitable for cultivation in southern regions and other arid zones.
The vegetative period of sunflower A 61 ranges from 107 to 115 days, ensuring timely harvest. Plants reach a height of 165-170 cm, feature large flat heads with a diameter of 18-24 cm, and have high leafiness. The 1000-seed mass is 61-62 grams, with a shell percentage of 99.7% and oil content ranging from 21-22%. Seed oil content is high — 50-52% — ensuring high-quality oil production. The genetic yield potential of this hybrid reaches 60 centners/ha, while average yields from trials amount to approximately 37 centners/ha.
Sunflower A 61 seeds are treated and processed to protect against diseases, promoting successful plant development and reducing yield losses. The recommended planting density is approximately 4 plants per linear meter. The hybrid exhibits low shattering and lodging resistance, facilitating harvest and improving the quality of the collected crop. Due to its characteristics and adaptability, sunflower A 61 is a reliable choice for intensive and sustainable sunflower oil production.
