Abstract: The current statusof GM crop（genetically modified crop）breeding and commercialization at home and abroad were reviewed. It was illustrated that the trend of GM crops development can not be halted. Speeding up will help to seize market opportunities and technical commanding heights while delaying will only miss the boat and pay a greater cost. The problems and challenges of GM crop development were discussed，in addition，three suggestions of promoting commercialization of GM phytase corn and Bt corn were made，i.e. adjusting and revising GMO regulation，drawing up a plan to speed up commercialization of GM corn as well as enhancing science communication and public opinion guidance.

Key words: GM crop（genetically modified crop）, crop breeding, GM phytase corn, Bt corn
