This hybrid is mentioned in scientific publications of the 1970s–1990s, where it most often serves as a model organism for studying water transport in roots, as well as the influence of potassium and abscisic acid on plant development.
In sunflower field trial materials, it is recorded that the hybrid underwent testing during which the seed oil content was determined, amounting to 39.9% in terms of dry matter. Detailed agronomic characteristics, including maturity group and disease resistance indices, are absent.
