The line is not an independent commercial variety for general agronomic use, but rather acts as a tool for breeding. It possesses high general combining ability, allowing it to pass valuable traits to progeny, including seed yield and oil content.
Within the framework of scientific research, the material is used to analyze the inheritance of morphological traits, such as plant height and head diameter. The characteristics of the line are manifested primarily in the composition of the hybrid progeny; therefore, maturity group or disease resistance indicators are not recorded for it separately.
