种子 科技浅析AOSCA种子认证体系在草种子生产中的应用

以北美官方种子认证机构协会（AOSCA）所制订的种子认证体系为基础，比较在野生植物种子采集或生产和栽培植物品种种子生产认证过程的具体应用。表明野生植物或栽培植物种子生产均需按照相应的认证程序，根据实际利用状况和培育目的具有不同的认证级别，并且各级别的认证种子均有明确的标签标识，保证植物材料或品种的遗传一致性。通过分析该体系在保证植物种子遗传稳定性和一致性方面的优越性和特点，为我国野生植物资源的收集利用、牧草种子的生产提供实践指导和借鉴经验，以促进我国草地生态建设和牧草种子生产的国产化。

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.
