Sunflower Ataman

Ataman is a medium-early hybrid of sunflower (Helianthus annuus L.) with high oil content and a classic plant type. It is characterized by high growth without branching, medium-sized leaves with green or dark green coloration, and medium blistered and serrated leaf margins. The florets are yellow-ligulate in oval shape, with orange tubular parts and weakly expressed anthocyanin coloration on the stigmas. The head is of medium size; at maturity, it hangs from being half-turned downwards to fully drooping. The seeds have an oval-elongated shape, medium thickness, and a black main color. The average oil content in the seeds reaches 49-53%, providing high oil content for the hybrid. Ataman is recommended for cultivation in various regions of Russia, including the North Caucasian, Middle Volga, and Ural regions. The vegetation period varies from 101 to 112 days depending on the region. The hybrid's yield is characterized by stability and high productivity: in the North Caucasian region, it is about 18.6-24.3 c/ha, in the Middle Volga region up to 27.4 c/ha, and in the Ural region about 11.2 c/ha. In some tests, the yield reached 35-45 c/ha, indicating the high potential of the hybrid. The mass of 1000 seeds varies from 48.5 to 60 g, which also depends on growing conditions. The Ataman hybrid has high resistance to a number of diseases, including phoma, sclerotinia, rust, and alternaria, as well as genetic resistance to new races of the tumbleweed parasite thanks to the Clearfield® Plus technology. The plant is distinguished by high germination energy, resistance to lodging, and a developed root system that ensures effective moisture use. These qualities make Ataman suitable for cultivation in various climatic zones, including steppes, forest-steppes, and forested areas, allowing for stable and high yields of oilseeds.
