What Are The Officially Approved Genetically Modified Crops Produced Or Imported By The State?

Genetically modified foods have always been the focus of attention. The list of genetically modified foods is not reliable? Are some so-called "identification methods of genetically modified crops" correct? What are the genetically modified crops officially approved by the state? On these issues, the people's Daily "verification" column interviewed the Ministry of agriculture and experts and scholars.

What are the transgenic crops in China?

Response: cotton, rice, corn and papaya have been approved for safety certificates; only cotton and papaya are commercially approved.

"Up to now, China has approved the safety certificate for GM production and has cotton, rice, corn and papaya in its effective period." Xie Jiajian, an associate researcher of the Institute of plant protection of the Chinese Academy of Agricultural Sciences, said that the issuance of the certificate was based on the application of the R & D person and the assessment of the safety committee of the agricultural genetically modified organisms. The safety certificate of transgenic production has been obtained, and commercial planting can not be carried out immediately. Xie Jiajian introduced that, in accordance with the requirements of the People's Republic of China seed law, GM crops also need to obtain variety approval certificates, production licenses and business licenses before they can enter commercial planting. "At present, GM rice and genetically modified maize have not yet completed the approval of the seed law, and there is no commercial planting." Xie Jiajian said, "the transgenic crops that have been commercially grown in China are only cotton and papaya."

China's genetically modified crops approved to import raw materials include soybeans, corn, rape, cotton and sugar beet.

Unlike traditional foods, GM?

Response: at present, Cherry Tomatoes, pepper, pumpkin and cucumber are not genetically modified foods.

A list of GM foods has been circulated on the Internet, including Cherry Tomatoes, big pepper, pumpkin and cucumber. Experts do not agree.

Wang Zhixing, a researcher at the Institute of biology of the Chinese Academy of Agricultural Sciences, said that the small tomato is also called Cherry Tomatoes and cherry tomato. It is a tomato variety from ancient times. It is only small because of its small size, inconvenient picking and low output. It was first used as an ornamental and was later found to be convenient to eat. Small size is a natural genetic difference, not a result of genetic modification.

Wu Gang, an associate researcher at the oil Research Institute of the Chinese Academy of Agricultural Sciences, said Cherry Tomatoes is closer to the wild state before artificial domestication. In fact, wild chestnut, walnut, apple and so on are far less than conventional cultivation varieties. These miniaturized varieties are derived from germplasm resources with ancestral primordial genes, which are not related to transgene.

Wu Gang said that little pumpkins and cucumbers are not genetically modified foods. They are just immature pumpkins and cucumbers. About the large colored pepper, Wu Gang said that the large colored pepper contains different types of anthocyanins, showing a richer color. The variation of anthocyanins is very common in plants, such as the same variety of flowers, and the radish also has carrot, green radish, white radish and so on.

Wang Zhixing explained that cotton, pepper, corn, rice and so on have different colors, which are natural genetic differences, not genetically modified.

Wu Gang said that all of these fruits and vegetables are conventional breeding methods, which are very easy to achieve.

There are some wrong ways to identify genetically modified foods.

[net] soybean soaked in water will not germinate, only expand.

[response] whether or not GM will sprout.

Wang Zhixing: whether genetically modified soybeans or non GM soybeans, if harvested after poor storage, or too long storage time, so that soybean seeds lose vitality, they will not germinate. All viable seeds, whether they are genetically modified or not, germinate at suitable temperature and humidity.

Transgenic tomato is bright red with hard fruit.

[response] there is no GM tomato in the market at present.

Wang Zhixing: at present, there is no GM tomato in our market. Our country has approved a kind of transgenic tomato resistant to storage, which can retard softening and decay. However, the safety certificate has expired due to poor taste.

[transgenic] potatoes are not black after peeling.

[response] there is no genetically modified potato in the world.

Wang Zhixing: after peeling potatoes, the blackening is caused by oxidation of polyphenols and phenols after encountering oxygen. The degree and speed of blackening were related to varieties, polyphenol oxidase content, storage conditions and storage time. Freshly harvested potatoes are generally not black enough to darken after long periods of low temperature storage. At present, there is no global market for potato varieties to reduce polyphenol oxidase by transgenic technology. China has not approved any GM potatoes to go public.

[net Chuan] except for greenhouses, other anti season foods are genetically modified.

[response] transgenic technology can not achieve off-season production.

Wang Zhixing: in addition to raising the temperature through the greenhouse to produce anti season foods, a large part of the anti season food is realized through off-site production and transportation. This has nothing to do with GM. At present, there is no ability to achieve anti season production through transgenic technology.

(net transmission) very few insect pests are genetically modified.

[response] genetically modified crops will also be attacked by pests, mainly by pesticides.

Wang Zhixing: insect resistance is one of the main traits of genetically modified crops. China's large-scale insect resistant cotton is transferred to the insecticidal protein gene Bt, and it can not be judged whether or not the pest is patronized.
