Variety description

10 August 2026

The code RUIY 5451 is used in international and industry documentation as a reference sample for conducting tests for distinctness, uniformity, and stability. Its primary role is to serve as a color reference point for expert assessment of pink flower color.

Available test guidelines contain no data on agronomic characteristics such as disease resistance or plant growth parameters. The variety does not appear as a commercial object with a detailed botanical description, remaining a tool for the standardization of expert assessments.
