Breeding line 2607 is used in scientific work to evaluate the combining ability of other lines. It was used in interspecific hybridization with wild Helianthus species to improve oil content and increase resistance to pathogens.
The line possesses genetically determined resistance to a number of diseases, while its susceptibility to certain races of Orobanche is noted. Characteristics typical for commercial varieties, such as plant height or maturity group, are absent in open publications.
