Abstract:The promotion of agricultural biotechnology research began in the 1980 s, has become the core technology in the field of agricultural scientific research, the agricultural genetically modified crops occupy market share increase year by year, effectively alleviate the national food shortage, environment pollution and the population problem. Recently, however, some of there is risk of genetically modified crops, the research of the toxicity of reports for the research and development of genetically modified crops casts a shadow. According to the data analysis, our country has not rejected gm"s capital. Therefore, to establish a set of perfect countermeasures of genetically modified crops safety assessment is particularly important. Were reviewed in this paper, the agricultural development countermeasures, food safety assessment of genetically modified crops, so as to perfect our system of the safety assessment of genetically modified crops provide certain support for genetically modified technology in the field of crop research and development for reference to healthy and stable development.
