The PH1MR line is not a commercial hybrid intended for direct sowing on a production scale and is classified as specialized breeding material. Genetically, the object is associated with the "Iodent" breeding group and is considered in the context of forming the gene pool of modern lines.
Within breeding programs, the line serves as a participant in crosses when creating new hybrid combinations. Detailed morphological characteristics of the material are not presented in open sources, as it is protected by intellectual property documents.
