The hybrid was created using interspecific hybridization methods involving wild sunflower species, such as Helianthus tuberosus and Helianthus argophyllus. Its introduction was of great importance for preserving the crop's plantings under conditions of Phomopsis epiphytotics.
Key characteristics of the hybrid are high field resistance to Phomopsis (Diaporthe/Phomopsis helianthi) and drought tolerance.
