Abstract: Seeds are important production goods in agriculture. There are clear requirements of the seed source, GMO status and seed treatment in organic agriculture. One of the purposes of this paper is to identify the requirements, development status quo of organic seeds and the risk assessment of whether the seeds could meet the organic standards. Through the data collection, the requirements, status quo and risk of seeds in organic crop production were analyzed. It is concluded that the seeds source is not the main risk factor of organic crop certification. The introduction of genetically modified seeds and seeds treatment are the main source of certification risk. The risk assessment of GMO is mainly based on its commercial cultivation and research status which determines the risk of GMO seeds. Whether seeds are treated with chemicals is also a significant risk in the use of conventional seeds. By analyzing the risks of organic seeds, this paper could provide the producers and inspectors with the precautions that should be paid attention to in the seed section to improve the compliance of organic production.
