The line is not intended for commercial cultivation and is not an independent commercial variety. It serves as a breeding tool and appears in the pedigree of other company lines used in the development of hybrid combinations.
Detailed descriptors for this line as an independent entity are absent from public sources. Within Pioneer breeding programs, selection was conducted based on traits of early flowering, plant height, oil content, and yield as part of the final hybrids.
