Ph9e4 is a specialized breeding material obtained through the process of repeated self-pollination to achieve genetic uniformity. This line is not intended for commercial production as an independent variety.
In breeding practice, the line is used in combinations with other forms to create hybrids. Detailed agronomic characteristics of the plant are not available in open publications, as the material is intended for internal use in breeding programs.
