H 865 RDGEY — an early-maturing sunflower hybrid intended for classic cultivation technology. It is characterized by high drought resistance and very high oil content reaching 54-56%, which significantly increases the economic efficiency of cultivation. The plants have compact sizes and an average height of about 175-180 cm, which contributes to lodging resistance and harvesting convenience. The head diameter is 20-23 cm, and the maturity period is about 110 days, allowing for flexible planning of agrotechnical activities.
The hybrid exhibits high resistance to various diseases, including phomopsis, phoma, rust, white mold, and peronosporosis, and is tolerant to new races of downy mildew. Special attention is given to resistance to sunflower rust (race A-F) and stem rot (race A-G), making it a reliable choice for cultivation in various regions with different moisture levels. The recommended sowing density varies depending on climatic conditions, allowing for optimized yield.
H 865 RDGEY is also characterized by tolerance to herbicides containing tribenuron-methyl, including preparations such as Gustar and Europa, which facilitates weed control and enhances the effectiveness of agrotechnologies. The potential yield of the hybrid reaches 5.5 tons per hectare, making it one of the leaders in the early-maturing sunflower group.
