Chinas transgenic technology started earlier, Chinas current GM
3、 technology level in the forefront of the world, especially made great achievements in the cultivation of new varieties of crops. In this paper, the status quo using gene transfer on Chinese agriculture and safety of transgenic technology are introduced, and the resolve of GM safety issues some thou
4、ght. On this basis, I made some new ideas of transgenic technology and application of transgenic technology development prospects were discussed. Keywords: GM technology; GM crops; GM safety issues; China Introduction:As the core of the biotechnology giant leap .Transgenic technology is known as the
5、 second “green revolution.“ In 1983, the worlds first strain of transgenic tobacco plants marks the arrival of the era of gene transfer plants. In the ensuing decades, genetically modified crops developed rapidly. In 2014, there are 28 countries in the world planted GM crops, the planting area has r
6、eached more than 180 million hectares, Chinese genetically modified crops planting area is 3.6 million hectares. With the widespread planting of genetically modified crops, the impact of transgenic technology in agriculture is growing. As the research of GM crops, China has made great achievements i
7、n the research of rice and cotton. The development of anything will not be smooth. With the development of GM technology, its security deposit issues also be exposed. The safety of genetically modified crops has been disputed by people, opponents argue that GM crops have great potential risk, it sho
8、uld be resisted. What is more, some people exaggerate the risk of genetically modified crops. Aroused peoples fear of genetically modified. In this paper, the people of GM crops concerns, the status of the development of GM crops were elaborated. Besides, security problems of genetically modified cr
9、ops and their solutions will be discussed. The current development of genetically modified crops in china GM refers to the Technology that use molecular biology method to transfer the artificial separation and some modified biological gene to other species and change the genetic characteristics of t
10、he species .Plant transgenic technology is the genetic transformation of plants, making plants to meet human needs in aspects of shape, nutrition and consumer quality. Chinas biotech crop improvement research began in the 1980s, during the past 30 years, Chinese agricultural and biological high-tech
11、 has been developing rapidly. At present, Chinas hybrid rice, cotton and other advanced in the world. GM technology Applied on cotton, rice and other crops on behalf of Chinas development status of GM crops.As a cotton producing countries, the industrialization of Chinese insect- resistant cotton ha
12、s brought huge economic and ecological benefits to Chinese society. Since the 1990 s, Chinas major cotton producing areas often suffered insect outbreaks and the effect conventional control is poor. In 1994, under the impetus of the country, Bt gene was successfully imported into The main plant cott
13、on species .China has become the second country with the independent development of insect-resistant cotton. In 1999, China began to commercial cultivation of cotton. In 2010, gm cotton planting and product in China reached 3.45 million hectares, accounting for 69% of the total cotton planting and p
14、roduct. The planting of insect-resistant cotton have effectively controlled the damage caused by the cotton bollworm .The insect-resistant cotton also reduced pesticide use, protect the farmland ecological environment. Cotton yield and growth of calendar year in China:Chinas research on genetically
15、modified (gm) rice have got rich achievements. In August 17, 2009, the Ministry of Agriculture promulgated transgenic rice security certificate for the two anti-lepidopteran pests transgenic rice -“Hua Hui 1“ and “Bt Shan You 63“ .In addition, China has produced the anti-amino phosphonic herbicide Bar gene rice lines, the new salt tolerance strains which represented by T22-77. Compared with ordinary rice, these transgenic rice has unmatched superior properties .It will bring huge economic benefits to Chinese farmers if these rice be planted on large-scale .For example, each
