Sunflower NS X 6773 is an early-maturing hybrid with a vegetation period of 95-98 days, exhibiting high drought resistance and resistance to various diseases. Plants reach an average height of 160-170 cm, have green leaves and yellow disc-shaped flowers. The hybrid is characterized by weak leaf pubescence and absence of branching, which contributes to compactness and ease of cultivation. Seeds have distinct marginal stripes, and the 1000-seed weight is approximately 59.2 g.
NS X 6773 exhibits high resistance to sulfonylurea herbicides, particularly tribenuron-methyl, facilitating weed control without harm to the crop. The hybrid is genetically resistant to numerous diseases, including frogeye leaf spot, gray and white mold, false powdery mildew, rust, sunflower moth, and seven races of broomrape (Orobanche cumana). The stem is resistant to lodging, enhancing yield reliability.
The yield potential of NS X 6773 exceeds 50 t/ha, with seed oil content ranging from 47-52%, and oil content reaching 48.7-49%. The optimal plant density per hectare is 55,000-60,000, ensuring maximum productivity. The hybrid is attractive to pollinators and exhibits high pollination rates, contributing to stable yield formation even under drought conditions. Due to its characteristics, NS X 6773 is a promising choice for cultivation in various regions with moderate climates.
