Rice is the most important staple food and the consumption is increasing in Europe and America. It is expected that the rice price will be increased due to the unstable supply and demand because of abiotic stress. Experts expect that the rice supply of Korea will be deficient in 2050 for the reason of global warming. Conventional breeding methods need to be supplemented with recent biotechnology to meet the problem such as growing population and climate change. Using rice biotechnology, a number of agronomically important traits and nutritional value have been improved. In this paper, the current situation of rice cultivation and production situation and supply and consumption in the major country were investigated to prepare future food security. Also the research trends of rice biotechnology and kinds of transformed rice as well as safety issues were reviewed by considering the scientific, social and economic values of rice.
