The line is a proprietary genetic material developed for use in corn breeding programs. It served as the basis for the development of other inbred lines, in particular PHWMM.
Detailed morphological descriptors and agronomic characteristics of the line are absent in open sources, as they are confidential information of the rights holder. The line is not intended for direct sowing as a commercial crop and is used exclusively as a breeding tool in the production of hybrid seeds.
