It is dual-purpose for medicinal and oil use. The flowers are orange-red at full bloom and turn red at the end of flowering. The tubular florets are long,and the flowering period is concentrated,making it suitable for mechanical harvesting. The average yield of dried flowers is 341.87 kg · hm^-2,with kaempferol and hydroxysafflor yellow A contents of 0.058% and 2.31%,respectively. The seeds are conical and glossy,with a thousand-seed weight of 35.66 g. The average seed yield is 3 570.11 kg · hm^-2,and the oil content is 26.4%. The growth period is 216 days. It exhibits strong tolerance to drought,barren soils,and saline-alkali conditions,along with broad adaptability. It is suitable for cultivation in safflower-producing areas of Henan Province and other regions with similar ecological conditions.
