【Abstract】 Transgernic crop breeding is a modern molecular breeding technique based on Biotechnologies such as in vitro DNA recornbination,genetic transforination and so on.Based on the results of infornation investigation,the paper briefly summarizes the essential conception and basic model of genetic engineering。It analyses the development and application of breeding high yield and high quality,insect-resistant,herdieide-tolerant and withstand worsening clirnates crops and points out the potential drarnatic impact of transgenic crop breeding on crop transgenic breeding development in China.The percpective and safety of genetic engtneering is discussed.更多还原
