Sunflower FS 75439

FS 75439 is an early drought-tolerant sunflower hybrid developed for cultivation in regions with short growing seasons and extreme climatic conditions. The hybrid belongs to the linoleic type and has high oil content, making it attractive for vegetable oil production. Plant height reaches approximately 152 cm, and the flower head diameter is about 15.9 cm, which contributes to good yield formation. The thousand-seed weight is 71 grams, indicating seed size and quality.

The FS 75439 hybrid is resistant to various biotypes of ragweed (A-G) due to the application of Clearfield and SUNEO technologies, providing protection against parasitic weeds and enhancing yield stability. Additionally, it exhibits high tolerance to Fusarium and new biotypes of downy mildew, along with genetic protection Mildew Control (MGP), which significantly reduces disease risks and yield losses.

This hybrid demonstrates adaptability to growing conditions, showing high drought tolerance and the ability to consistently produce yields even under adverse weather conditions in southern regions. Its early field clearance allows its use in crop rotation, particularly as an excellent preceding crop for wheat. The recommended seeding rate varies from 45 to 53 thousand seeds per hectare depending on soil moisture levels, promoting optimal plant development and maximizing yield.
