RHA SNRF is an inbred sunflower line included in the State Register of the Russian Federation and intended for cultivation in all regions. The plant is of medium height, fully branched, with a medium-sized green leaf and weak blisteriness. The sunflower head is small, semi-downward-facing, with a straight stem and slightly convex seed surface. The seed is broadly ovoid, of medium thickness, brown in color without distinct stripes or spotting. Flowering occurs at medium maturity; ray florets have an orange-yellow tint, while tubular florets are yellow with anthocyanin discoloration of the style. The hybrid is distinguished by high disease resistance, including high immunity to downy mildew and resistance to six common races of verticillium wilt. RHA SNRF is tolerant to a single application of the herbicide Granstar at a dosage of 50 g/ha, which facilitates weed control in crops. Plants exhibit high initial growth energy, thick stems, and a powerful root system, ensuring lodging resistance and high drought tolerance. The hybrid responds well to fertile soils and intensive cultivation technologies, demonstrating uniform flowering and maturation. The vegetative period is approximately 110-112 days, allowing for yields up to 52 centners per hectare at a planting density of 50-55 thousand plants per hectare. Plant height reaches up to 175 cm, and oil content in seeds varies from 48 to 50%. Due to its characteristics, RHA SNRF is a profitable choice for agrarians seeking high profitability and quality sunflower harvests under various climatic conditions.
