Don Officials with the polygraph technique to save a life Chinese harvesting olives star Li Jing reproduced hydraulic Forum: genetically modified food has been great concern, circulated on the Internet, "genetically modified food" list do not fly? Some so-called "identification method of genetically modified crops" accurate? State formally approved the production or import of genetically harvesting olives modified crops have? On these topics, the People's harvesting olives Daily, "proof" column reporter interviewed the Ministry of Agriculture and experts. Of genetically modified crops have? Has approved the safety certificate cotton, harvesting olives rice, corn and papaya; only cotton, harvesting olives papaya planting harvesting olives approved trade "Up to now, China's approval of GM crop production and application security certificate within the validity period of the cotton, rice, corn and Fan Papaya. "Chinese Academy of Agricultural Sciences Associate Professor Xie Jian introduced, issuing certificates is based on the application and the Commission's assessment of genetically modified organisms safety research and development of people, after a joint meeting discussed and adopted harvesting olives by the ministerial approval. Approval certificate information already on the website the Ministry harvesting olives of Agriculture announced the approval of each batch of the situation harvesting olives can be queried. Made transgenic production application security certificates, and not horse trade long cultivation. Xie Jian introduced, in accordance with the requirements of the "Republic of China Seed Law" of transgenic varieties of crops also need to obtain approval certificates, business harvesting olives licenses and production licenses, in order to enter the business of planting. According to "The main crop varieties validation approach" to apply for validation certificate shall have the following varieties premise: artificial breeding or discovery via improved; significant differences with existing varieties; genetic traits harvesting olives chaos; consistent morphological and biological harvesting olives characteristics; having conform " agricultural plant species named after delimitation "of. Production licensing, business licensing are subject to review comments made by the head of the local provincial corporate registration of agricultural administration. "At present, transgenic rice and genetically modified corn seed law has not yet completed the approval delineated, no trade cultivation. "Xie Jian said," China has trade cultivation of GM crops only cotton and papaya. "Our entrance is used as raw materials harvesting olives for processing approved GM crops are soybean, corn, canola, cotton and sugar beet. These foods necessary to get our country's security certificate. It is understood that China formulated the "genetically modified organisms entrance security governance approach", "genetically modified organisms approval process," the "entry-exit inspection and quarantine GMO governance approach" and "genetically modified organisms identity management approach", designated county The above part of the local government harvesting olives responsible for agriculture monitoring harvesting olives of GMOs identity governance, the AQSIQ is responsible for the entrance examination to verify the identity of agricultural GMOs ports. According to reports, these governance rail system to get a better implementation harvesting olives of the logo should be the standard to make standard. Different from the traditional food is genetically modified? Currently marketed cherry tomatoes, bell peppers, pumpkin, cucumber is not a genetically modified food genetically modified foods circulated online lists, harvesting olives including "cherry tomatoes, bell peppers big guys, small pumpkins, cucumbers." Experts do not agree on this. Chinese Academy harvesting olives of Agricultural Biotechnology researcher Wang Zhixing say tomato, also known as cherry tomatoes, cherry tomatoes, a tomato varieties since ancient times, only because of the small size, picking inconvenience, low yields, first only as an ornamental, edible facilitate later found, After gaining popularity harvesting olives through improved taste. Small size is generated by genetic differences, harvesting olives the results are not genetically modified. Chinese Academy of Agricultural Sciences, said Wu Gang, associate researcher of oil, cherry tomatoes closer to the domestication of wild state before harvesting olives really harvesting olives wild chestnuts, harvesting olives walnuts, apples, are also much smaller than conventional cultivars. Human domestication of wild plants in general is to increase production, the main approach is to increase the fruit, but with the diversity of the food requirements of the people, thrown a lot of small fruits and vegetables, harvesting olives such as watermelon, ruby spring. These compact varieties are derived from the original ancestral gene with germplasm resources, regardless of the transgene. Wu Gang said, small pumpkins and cucumbers are not genetically harvesting olives modified harvesting olives food, just not fully ripe pumpkins and cucumbers. If inheritance in the field planting, small pumpkins and cucumbers will eventually grow into a big pumpkin and ordinary old cucumber. About the big guys bell peppers, Wu Gang, said the big guys bell peppers contain different types of anthocyanins, showed a more fruitful harvesting olives colors. Anthocyanins variation is common in plants, like flowers unified varieties have different colors, radish carrot, green radish, white radish. "Our anti-viral had been approved planting sweet pepper trade, but compared with conventional bell pepper, sweet pepper and transgenic no significant advantage, so naturally harvesting olives eliminated by the market. "Gang said, in some species, or even replace the color mutation of wild colors, mainstream cultivars, such as raw carrots mostly harvesting olives in purple, orange carrots are the most common is the Dutch breeders breeding under Dutch flag colors out. Therefore, the market in the sale of fruits and vegetables, harvesting olives the color has nothing to do with genetically modified. Wang Zhixing explain genetic differences between different colors of cotton, peppers, corn, rice, etc., are naturally occurring, not the result of gene transfer. Like ancient colored cotton there, but because of the color of cotton fiber is short, intensity difference, in the past few planting, and now the department because they do not stain attract consumers, farmers started harvesting olives planting. Colored peppers are also naturally occurring, but not large-scale cultivation in the past, the average consumer rarely seen. Wu Gang said that these fruits and vegetables are very easy to do conventional breeding methods, using genetically harvesting olives modified but is not economical approach. "Conventional breeding is mainly obtained by breeding new varieties with new traits. There is a very important job is to "choose." Naturally occurring genetic variation, and often occurs randomly. "Gang explains," No matter the size, color, natural mutant harvesting olives of the natural world, can be found. Breeders do the job just to find these mutants, and other good traits polymerization harvesting olives together into varieties. "Wu Gang, the first volume, tomatoes, harvesting olives bell peppers, squash, cucumbers at home and abroad have studied and obtained transgenic transgenic plants, which only won tomato and sweet pepper cultivation worldwide trade approval. National Trade planting genetically modified tomatoes are the United States harvesting olives (six kinds), Mexico (three kinds), Japan (one kind), China (one kind, "Hua Fan One") and so on. Wu Gang explained, there is no extension of the early ripening tomatoes, ripe tomato transgenic extension contains a long upwind. But with the development harvesting olives of technology, breeders have obtained an extension of the non-transgenic ripe tomato, transgenic tomato bears the upper hand in terms of longer, lower production has become a big problem, because of the thick-skinned poor taste, directly out of the market. "Since harvesting olives 1998, the world has no new approved the commercialization of transgenic tomato planting. In China, the transgenic tomato has been withdrawn from the market. "Gang said.
