Abstract: Test guideline of distinctness，uniformity and stability（DUS）for Salvia L. was developed referred to the International Union for the Protection of New Varieties（UPOV）of Plants’s guideline（TG/361/1），and followed technical specification of the plant variety specific（discriminatory），consistency and stability testing. After collecting and testing 22 Salvia plant materials，47 test characteristics were finally determined. Based on the UPOV guidelines，one characteristic was added，two characteristics were redefined，the expression status of 10 characteristics and the method of observation of 5 characteristics were adjusted，and some measurement details were adjusted. This guideline is suitable for testing ornamental Salvia L.（except for Salvia splendens Ker-Gawleror and Salvia miltiorrhiza which guidelines have been published）. All the tested species could be clustered into 3 groups by 13 quantitative characteristics，and all the tested S. nemorosa cultivars were clustered in group 1. It was suggested that these 13 quantitative characteristics were useful for judging distinctness for Salvia L.
