The line was obtained by breeders through inbreeding and repeated self-pollination. In breeding programs, this material is used as a reference object when evaluating hybrids for productivity and resistance to adverse conditions.
Detailed agronomic characteristics of the line are not available in open publications. Available data are limited to mentions in patent documentation, where Phdn7 is considered in the context of comparisons with other inbred lines regarding pollen shed intensity and tassel size parameters.
