Sunflower AS 35151

AS 35151 — hybrid sunflower (Helianthus annuus L.), intended for cultivation in the Ural and West Siberian regions. The plant is characterized by high stature, reaching approximately 170 cm, absence of branching, and green leaf color. Ray flowers are yellow, and seeds exhibit distinct marginal stripes. The vegetation period of the hybrid ranges from 90 to 130 days depending on the region, classifying it as mid-early or late-maturing under different cultivation conditions. Hybrid AS 35151 possesses high drought resistance and resistance to major sunflower diseases. It is genetically resistant to race A–E of downy mildew, resistant to white mold, moderately resistant to false powdery mildew, as well as to gray and dry rot. The 1000-seed mass varies from 60.9 to 70.3 grams, and oil content in the seeds reaches 47.7%, ensuring high oil content at the 48–50% level. The potential yield of the hybrid is 42–45 centners per hectare, with average yields in the West Siberian region reaching 19.8 centners per hectare and in the Ural region — 17.1 centners per hectare. The recommended seeding rate is 55–60 thousand seeds per hectare, promoting optimal plant development and achieving maximum productivity. The hybrid is suitable for conventional cultivation techniques and is recommended for cultivation in regions such as the Republic of Bashkortostan and Altai Krai. Due to its agronomic characteristics and disease resistance, AS 35151 is a reliable choice for farmers seeking high and stable sunflower yields.
