Abstract: Plant variety distinctness, uniformity and stability testing (DUS testing for short) is necessary for variety protection, examination and registration. The preparation of DUS test guideline for eggplant (Solanum melongena L.) will provide scientific basis for testing and substantive examination of varieties. Following the general principle of GB/T 19557.1 and using the UPOV TG/117/4 as reference, by field experiments with 243 eggplant varieties and several times revision, we have finished the DUS test guideline for eggplant (National Standard Draft). In the guideline, 42 testing characteristics and description method were confirmed; meanwhile, 20 example varieties were screened and the principle for distinctness, uniformity and stability of eggplant was defined. The guideline provided technical standard for variety description and distinctness, uniformity and stability of eggplant DUS testing in China. This paper gave detailed description of compilation principle and procedure for the test guideline, selection of characteristics and example varieties and assessment of DUS.
