2. For the non-essential crop varieties that are applied for certification, the comparison tests of the varieties in at least two production cycles shall be completed, and the test results shall reach the standards for species identification.

3. For the main crop varieties that are applied for introduction and examination, the introduction test (formal test) of the varieties should be in progress.

4. The CMS lines of rice and other crops that are applied for identification should have at least one matching group of varieties to complete a variety of regional trials for a production cycle, and the test results will reach the certification standards for the varieties. For the two-line sterile lines of rice, the identification results of artificial climate boxes issued by China Rice Research Institute or Huazhong Agricultural University should be provided, and the identification results should reach the validation standard for sterile lines.
