FR 85509 — a high-yielding sunflower hybrid, characterized by high resistance to major diseases and pests, as well as tolerance to dense planting. This hybrid features good drought resistance and comprehensive resistance to the A-G+ strains of the sunflower moth, ensuring stable yields even under challenging climatic conditions. The vegetation period is 115-120 days, and plant height varies from 170 to 185 cm depending on the growing region and cultivation conditions. Thanks to its well-developed root system and strong stem, FR 85509 exhibits high resistance to lodging, facilitating harvest and reducing yield losses.
The hybrid is adapted for use with imidazolinone herbicides such as Euro-Lightning, allowing effective weed control without harming the crop. It is recommended for cultivation in various agroclimatic zones, including Steppe, Forest-Steppe, and Polесье, making it a versatile choice for farmers.
The optimal planting density is 55-60 thousand plants per hectare, which helps maximize the hybrid’s potential and achieve yields of 5-7 tons per hectare.
Sunflower FR 85509 is the result of breeding work aimed at developing high-quality seed material adapted to growing conditions and agricultural market requirements. Its high productivity, resistance to stress factors and diseases, and compatibility with modern protection technologies make this hybrid a profitable and reliable choice for farmers seeking stable and high yields of oilseed crops.
