Abstract

The guidelines for the Distinctness, Uniformity, and Stability (DUS) test for new perennial savory (Satureja spp.) cultivars have been prepared and compiled in accordance with the principles of the International Union for the Protection of New Varieties of Plants (UPOV) and the national regulations of Iran. The process of drafting these guideline, including the selection and determination of traits to be assessed, the determination of the states of expression of these traits and their range of variations, the ordering of traits, and the methods for evaluating distinctness, uniformity, and stability, are described in this article. In this guideline, fourteen traits are tested, including three qualitative traits (QL), one pseudo-qualitative traits (PQ), and ten quantitative traits (QN). Additionally, the range of variation for the expression of some quantitative traits has been quantified in this guideline. Among the fourteen traits tested, four traits were selected for grouping the cultivars, and four traits were included in the technical questionnaire. This new guideline for the DUS test of perennial savory (Satureja spp.) is intended for the identification and registration of new cultivars of this plant and the granting of breeders' rights.
