The plant has medium height, no branching, and a half-downward-facing flower head with a curved stem and medium size. Leaves are medium-sized, green, with moderate serration and weak blistering. Seeds are broad-oval in shape, medium-sized, with primary black coloration and weak gray stripes. Flowers are yellow, tongue-shaped, tubular, and lack anthocyanin staining on the stigma.
The hybrid has a high yield potential up to 5.4 t/ha (54 c/ha) and oil content of 50-53%. It is resistant to major diseases, including downy mildew (tolerance A-G+), as well as lodging and high temperatures. Due to these qualities, FS 71801 is a reliable choice for cultivation under the herbicide Granstar, ensuring stable and high yields across various regions.
