< p > recently, according to media reports, the Ministry of Agriculture approved two import licenses of genetically modified cotton this year.

Genetically modified crops have always been the focus of attention of the media and the public. With regard to the approved import of these genetically modified crops, a spokesman for the agricultural genetically modified organisms safety committee recently said through the Ministry of agriculture website that China's safety assessment of these new pgenic varieties is very prudent, and it has been three years since the application to obtain the certificate.

Monsanto Company has inserted pgenic cotton plants into pgenic cotton plants, and has been tested with Agricultural Research Bureau and some university scientists for two years.

The development of pgenic cotton in China has gone through a period of time.

Starting from the "95" plan, the research on "insect resistant cotton" has been set up as a major project by the national "863" plan, and further studies on monovalent genes, bivalent genes and polyvalent insect resistant cotton are also carried out.

At present, many pgenic cotton varieties have been approved.

< p > in addition to the research on pgenic disease resistance and insect resistant cotton, our country has also carried out other aspects of pgenic research, such as the closest animal keratin pgenic cotton made by Professor Chen Xiaoya, Professor of Chinese scientists. It is about to turn the keratin of rabbit and wool into cotton a target= "_blank" href= "//m.pmae.cn/" > strong > cloth > /strong > /a >, which has been awarded the national patent.

The animal keratin gene is introduced into cotton fiber to make it express specifically, so that the cotton fiber can be improved. It has good gloss, soft handle, good elasticity and strong heat preservation. It not only retains the natural essence of traditional cotton, but also has the characteristics of wool < a target= "_blank" href= "//m.pmae.cn/" > strong > textile < /strong > /a > product.

< p > according to the annual report issued by the international agricultural biotechnology service organization (ISAAA) in March this year, the top five countries in the world are the United States, Brazil, Argentina, Canada and India. The sixth place is China. The domestic planting area is 4 million hectares, mainly for insect resistant cotton.

According to relevant news, up to now, the Ministry of agriculture has approved the import of GM crops this year, including three kinds of soybeans, two kinds of corn and two kinds of cotton.

The three pgenic characteristics of soybean were herbicide resistance, insect resistance and insect resistance herbicide, and the approved time was June 6, 2013.

Among them, two kinds of cotton are characterized by herbicide resistance and insect resistance.

The above seven kinds of crops are used for processing raw materials. They are Monsanto Esprit Far East Limited, Syngenta crops protection company and Basf The Chemical Company.

Among them, Monsanto Esprit Far East Limited is a large importer of genetically modified crops. Most of the imported genetically modified crops approved since 2012 have been sent to trial.

< p > the effective period of the import of the seven pgenic crops is from 2013 to 2016 or 2018.

Reporters on the 2012 GMO approval table showed that last year there were 12 approved GM crops, including cotton, soybeans, corn and rape. The main pgenic characteristics were insect resistant and herbicide resistant.

The approval form was published on the website of the Ministry of agriculture in June 18th.

Less than P, however, opponents argue that GM crops have not been born for a long time and are not enough to prove that they have no side effects on the human body and environment, and that the import of large quantities of genetically modified crops is also likely to impact traditional agriculture.

Because of the obvious advantages and disputes of genetically modified crops, China has adopted a conservative import system for overseas genetically modified crops, that is, the limited import under the approval system. The contents of the examination include the environmental safety, safety, safety level and approval status of overseas crops.

In addition, commercialization of GM food crops has not yet been liberalized and commercial seeds are not allowed after the introduction of genetically modified grain seeds.
