FS 71508 Sunflower is an inbred line characterized by medium-sized plants and a lack of branching. Leaves vary from small to medium, dark green in color with blistering ranging from weak to medium and serration from fine to medium. The leaf cross-section is concave; the leaf tip can range from broadly triangular to rounded, with large auricles. Stem hairiness in the upper part is medium. Flowering occurs at medium maturity. Ligulate florets are narrowly egg-shaped, medium length, and yellow; tubular florets are orange with anthocyanin-colored stigmas. The head is semi-downward-facing, medium-sized, with a straight stem and a slightly concave seed side. The seed is small, broadly egg-shaped, medium thickness, primarily black with distinct gray marginal stripes. The FS 71508 hybrid is distinguished by high oil content, reaching 50–53%, ensuring high economic efficiency when cultivated. Potential yield can reach 54 centners per hectare, making this sunflower attractive to agronomists seeking maximum returns even under limited moisture and high temperatures. The plant exhibits high drought and heat tolerance, allowing successful cultivation in stressful climatic conditions. A feature of this sunflower is its resistance to downy mildew (Cercospora helianthi), including a wide range of parasite strains (A–G+), which significantly expands its usage possibilities in regions at high risk of infestation. Thanks to these qualities, FS 71508 is suitable for cultivation under herbicides based on Graminada, facilitating crop care and increasing their productivity. All these characteristics make FS 71508 a reliable and profitable choice for modern agricultural enterprises.
