Analysis on the application of AOSCA seed certification procedures in the forage seed production

Based on the seed certification procedures, the AOSCA established, this paper aimed to compare the certification procedures of seed collected or produced in wild plants and cultivar seed produced in the cultured plants. It showed that there were different procedures for seed certification to produce seeds of wild or cultivar plants. The certified classes prescribed in the wild and cultivar plant were different according to the utilization in the practice and breeding purpose. The determined labels were matched with each certification class, and were able to ensure the genetic consistency in wild or cultivar plants. The advantage and specialty, revealed on the guarantee of seed genetic stability and variety identity in the seed certification, can provide the instruction to practice and the experience to refer for the collection and utilization of wild plant resource and the production of forage seeds. Once the seed certification would be introduced and brought into effect in China, it could promote the revegetation of grassland ecosystems in large scale and the forage seed production.
