The sunflower hybrid Valkyria is a medium-early intensive variety with a maturation period of 96-98 days, belonging to the early-maturing group. It is characterized by a high degree of self-fertility and adaptability, which ensures stable crop formation under various conditions. The plant stem is of medium height — 160-180 cm, and the head diameter is 20-24 cm. The hybrid is resistant to lodging and withstands drought well, making it a reliable choice for cultivation in complex climatic conditions. Valkyria boasts a high oil content in seeds at 52-53%, while its genetic yield potential reaches 38-40 centners per hectare. Average yield varies depending on weather conditions and region, typically ranging from 25 to 32 centners per hectare, with some regions achieving maximum figures of 35.2 c/ha. Fat content in seeds falls within the range of 50.3-54.4%, confirming the high oiliness of the hybrid. The hybrid possesses field resistance to major pathogenic diseases, including downy mildew, rust, white mold, as well as dodder and flower parasite. Moreover, Valkyria demonstrates relative tolerance to Phoma, sunflower moth, and cotton bollworm. High productivity potential combines with resistance to biotic and abiotic stresses, as well as the ability to withstand planting thickening. Hybrid seeds undergo treatment with preparations Apron, Maxim-XL, and Agromix, which improves germination and protects plants during early development stages.
