Sunflower SAINT GEORGE

SAINT GEORGE — a sunflower hybrid (Helianthus annuus L.), intended for cultivation in various regions of Russia, including the Central Black Earth, Volga, North Caucasus, as well as Stavropol and Krasnodar regions. The plant is characterized by medium height, absence of branching, and green leaf coloration. The flowers are yellow, tubular, and the leaf pubescence is weak, contributing to good resistance to adverse conditions. Marginal stripes on the seeds are either absent or very weakly expressed, which is a distinctive feature of this hybrid.

Maturity periods vary from mid-season to late-season, with a vegetation period ranging from 120 to 136 days depending on the growing region. The hybrid’s yield is characterized by stability and high productivity: in the Central Black Earth region, average yield reaches 31.0 c/ha with a maximum of 41.9 c/ha; in the Volga region — average 24.7 c/ha and maximum 45.0 c/ha; in the North Caucasus region, average yield is 24.8 c/ha with a maximum of 42.4 c/ha. The 1000-seed mass varies from 48.5 to 53.0 grams, indicating large seed size and quality.

The oil content in SAINT GEORGE seeds is high — ranging from 46.3% to 51.1% — ensuring high oil extraction (approximately 12.6–12.7 c/ha). The hybrid exhibits good resistance to dry rot and rust, but is susceptible to white mold, requiring attention during agronomic practices. Due to its characteristics, this sunflower is suitable for oil production, providing high-quality raw material for food industry, as well as for technical applications and animal feeding.
