Sunflower Doloris SU

Sunflower Doloris SU is a medium-maturing hybrid with a vegetation period of 114-118 days and plant height ranging from 165 to 175 cm. It features a strongly convex flower head with a diameter of approximately 17 cm and a 1000-seed mass of 54-58 g. This hybrid is intended for oil production, with oil content in seeds reaching 47-49%. Its yield potential is up to 5.2 t/ha under optimal growing conditions, making it an attractive choice for agricultural producers in the forest-steppe zone.

Doloris SU exhibits high resistance to major sunflower diseases, including white and gray mold, powdery mildew, rust, and phomopsis, with resistance ratings of 8 to 9 points. It also shows high resistance to lodging and shattering, which helps preserve yield. A distinctive feature of this hybrid is its resistance to all volunteer species of the parasitic plant volunteer (A to G), as well as tolerance to herbicides containing tribenuron-methyl (SU), which simplifies weed control and allows for the application of the Express technology.

The hybrid demonstrates rapid early growth, heat and drought tolerance, ensuring stable high productivity across various soil-climatic conditions. Recommended preceding crops for planting are potato, corn, and winter wheat. Seeds are supplied in packages of 150,000 units and require storage at a humidity of 5-6% and temperature not exceeding 10℃. Doloris SU is versatile in application and suitable for cultivation in the forest-steppe zone, ensuring a reliable and high-quality oilseed sunflower harvest.
