Abstract: At present, only transgenic cotton and papaya are grown in China with large area. Although a few transgenic staple crops varieties, such as rice and maize, had been granted safety assessment certificate for nearly 7 years, they have not been used for commercial use now. In contrast to that, large amounts of maize and soybean products are imported to China every year, and most of them are genetically modified (GM) products. That is because, on the one hand that the current atmosphere of public opinions on GM crops and the research and development status of GM crops in our country require us to be prudent and cautious to advance transgenic staple crop commercialization; on the other hand, global development tendency, yield\|enhancing potential, economic and environmental benefits, and our countrys basic strategy to gain high ground in this agriculture high-tech field as well as the domestic market demand  of GM crops commercial use require us to speed up the commercialization process of GM staple food crops. How to resolve this contradiction and to carry out transgenic staple food crop development and commercialization smoothly in China, it is now one of our main tasks at present. Therefore, it is necessary to discuss the current status, problems and countermeasures of commercial use of GM staple crops in China, hoping to provide reference for realizing GM staple food commercialization in our country in the near future.
