Plants have a medium height of about 175 cm and a robust, branched root system capable of extracting moisture from depths up to 3 meters, which contributes to the hybrid’s adaptability to various soil types and climatic conditions. The sunflower head is large, up to 25 cm in diameter, fully filled with seeds of thin and convex shape.

The hybrid exhibits high resistance to a complex of diseases, including false powdery mildew, fomopsis, peronosporosis, white and gray rot, as well as four races of downy mildew. Thanks to its low maintenance requirements and ease of seed processing, Arsenal OR is a reliable choice for farmers seeking high-quality sunflower yields with good oil content.
