Introduction

In 1997, in order to protect the rights of new plant varieties, encourage the cultivation and use of new plant varieties, and promote the development of agriculture and forestry, my country issued the "Regulations of the People's Republic of China on the Protection of New Varieties of Plants". In 1999, my country joined the International Union for the Protection of New Varieties of Plants (UPOV) and became a 39th member. Distinctiveness, uniformity and stability (DUS) are the basic attributes of varieties, and DUS testing is an important basis for granting variety rights. In order to standardize the order of the seed market, in 2015, when the "Seed Law of the People's Republic of China" was revised, the DUS test was used as a variety approval and registration method. Note the preconditions.

For DUS testing of new plant varieties, the testing guidelines are usually developed on the basis of plant genus or species. Due to the wide range of plant classification, different plant genera the phenotypic differences between species are large, and it is difficult to construct a standard for DUS testing for all species. Therefore, GB/T 19557 is divided into several parts, each part specifies the test traits and points of a plant. GB/T 19557 is proposed to consist of 33 parts.
