LG 50545 CLP is a mid-season sunflower hybrid developed by Limagrain Europe SA through selection using parental forms F7AX2MK and R890MJK. The plant is characterized by high stature (approximately 90-100 cm) and medium-sized flower heads with a diameter of 17-18 cm, which orient themselves half-downward when mature. Seeds are black with poorly defined gray marginal stripes; the 1000-seed weight ranges from 35.6 to 63.7 g depending on the growing region. The hybrid features green leaf coloration and no branching, contributing to plant compactness and ease of agronomic management. LG 50545 CLP is optimized for the Clearfield® Plus system and exhibits high resistance to the herbicide Euro-Lightning Plus as well as to downy mildew. It demonstrates high drought, lodging, and shattering resistance, making it a reliable choice for various climatic conditions, including steppe and forest-steppe zones. The vegetative period is approximately 117 days, allowing the hybrid to successfully adapt to regions of the North Caucasus, the Lower Volga, Rostov Oblast, Krasnodar Krai, and certain steppe zones of Ukraine and Kazakhstan. LG 50545 CLP stands out for its high yield and quality characteristics. The average seed yield in the North Caucasus region reaches 24.3 t/ha, and in Pavlodar Oblast — 7.4 t/ha, exceeding standard benchmarks by 31.3%. Oil content in seeds varies from 47 to 48.7%, and the hybrid is high-oleic, with oleic acid content in oil ranging from 77.1 to 83.7%. Oil yield per hectare ranges from 7.4 to 11.3 t/ha, making this hybrid attractive for producing high-quality sunflower oil with improved technological properties.
