Eight transgenic maize varieties

transgenic corn 1. transgenic insect-resistant corn Bt-176 transgenic corn Bt-176 has the characteristics of resistance to LEPIDOPTERA, especially corn borer and glufosinate herbicide. Bt-176 corn has been widely planted in Japan (1996), Canada (1996), Argentina and EU member States (1997) since the United States allowed unrestricted planting for the first time in 1995, and has been widely used as food and feed. 2. Transgenic corn NK63 Transgenic corn NK63 is a genetically modified corn developed by Monsanto Company in the United States. Through transgenic technology, this kind of corn is resistant to the glyphosate herbicide "Roundup" produced by Monsanto. However, the research team of Kane University found that the experimental mice fed NK63 and the feed contaminated by "Roundup" had a very high proportion of tumors and other visceral injuries. Genetically modified corn variety 3. Genetically modified corn MON81 Genetically modified corn MON81 is a variety developed by Monsanto in the United States, but the French authorities have announced that it is forbidden to grow, use and sell genetically modified corn MON81 from Monsanto in the United States. The main reason is that MON81 transgenic corn will do harm to the environment. 4. Transgenic phytase maize BVLA4311 According to the audit information published by China Biosafety Network, the phytase transgenic maize BVLA4311 declared and approved by China Academy of Agricultural Sciences is currently mainly produced and applied in Shandong Province, and the safety certificate is valid from August 17, 29 to August 17, 214. 5. Other genetically modified corn varieties. The relevant departments stopped selling a batch of suspected transgenic corn seeds, namely Shibin 338, Jinqing 77, Jinqing 79, Jinqing 129, Jinqing 168, Hong Chen 788, Pengcheng 8, Pengcheng 5, Fuer 216, Fuer Yuwo 116, Qiao Jing 67, Tayu 1, Dika 1, Dika 3 and Yuanfa 86. What are the varieties of genetically modified corn? Genetically modified corn is prohibited from being planted and sold by the state, so growers must not buy these genetically modified corn varieties introduced above when buying corn seeds. For the first time in ten years, three domestic genetically modified corn and soybeans have obtained biosafety certificates. On January 21st, the Department of Science, Technology and Education of the Ministry of Agriculture and Rural Affairs released the approved list of safety certificates (production and application) of agricultural genetically modified organisms in 219, including two maize varieties and one soybean variety. This is the second time that two kinds of rice and one kind of corn obtained the safety certificate of genetically modified organisms in 29, and another major crop variety obtained the safety certificate of genetically modified organisms. The two maize varieties approved this time are "insect-resistant and herbicide-resistant maize DBN9936 with cry1Ab and epsps genes" from Beijing Dabeinong Biotechnology Co., Ltd. and "insect-resistant and herbicide-resistant maize Ruifeng 125 with cry1Ab/cry2Aj and g1evo-epsps genes" from Hangzhou Ruifeng Biotechnology Co., Ltd. and Zhejiang University (formerly known as "Shuangkang 12-5"), which are suitable for ecological areas. The soybean variety is SHZD321 with g1evo-epsps gene transferred from Shanghai Jiaotong University, and the suitable ecological area is the southern soybean area. The safety certificate is valid from December 2, 219 to December 2, 224. Make breakthroughs in important traits. The paper reporter noticed that Shuangkang 12-5 corn and DBN9936 corn were the first batch of transgenic insect-resistant and herbicide-resistant corn varieties that obtained the safety certificate of agricultural genetically modified organisms in China. Its insect resistance and herbicide resistance can be effectively applied to agricultural pest control and weed control. In 29, the former Ministry of Agriculture issued a safety certificate to the domestic transgenic phytase corn "BVLA4311". However, the main function of this trait is to reduce the anti-nutritional effect of phytic acid, thus improving the utilization efficiency of phosphorus and nutrients such as calcium, magnesium, manganese, iron or amino acids, and reducing the discharge of high-phosphorus feces. Shen Zhicheng, head of the R&D team of genetically modified corn in Zhejiang University, told the paper (www.thepaper.cn) reporter that the control effect of Shuangkang 12-5 corn on corn borer was 96%, which was 6%-1% higher than that of the control. "This increase in production is achieved by reducing the loss of pests, and the loss of corn borer can basically be reduced to zero." He added. Danone's announcement on the evening of January 21st showed that DBN9936 corn had good resistance to the main LEPIDOPTERA pests such as corn borer, and at the same time it could tolerate four times the medium dose of glyphosate recommended by the label. Its glyphosate resistance meets the actual requirements of maize production in China, and can provide efficient, safe, flexible and low-cost weed solutions for maize growers. Dabeinong said that the issuance of the safety certificate of insect-resistant and herbicide-resistant corn varieties with agricultural genetically modified organisms will be a major technological upgrade of China's corn industry, and the application of transgenic technology will increase the comprehensive income per mu of corn planting by at least 1 yuan. Therefore, the industrialization of genetically modified corn will have a significant and positive impact on farmers' planting benefits and the healthy development of corn seed industry, as well as the demand for high-quality corn raw materials by downstream feed breeding enterprises. At the same time, it is of strategic significance to the adjustment of field crop planting structure and food security in China. With regard to genetically modified soybeans, Professor Cao Yueping from the College of Agriculture and Biology of Shanghai Jiaotong University introduced the herbicide-resistant effect of transgenic soybean SHZD32-1 in the article "Study on glyphosate resistance and glyphosate herbicide control effect" in Soybean Science in 218, that is, under the treatment of 1~4 times glyphosate field concentration, there was no significant difference in plant height and coverage, and there was no obvious effect on growth. The market is enthusiastic. On December 3, 219, the Department of Science, Technology and Education of the Ministry of Agriculture and Rural Affairs issued the "Announcement on the Naming of 192 Genetically Modified Plant Varieties such as CiKJH83" in official website, and it is planned to approve the issuance of agricultural genetically modified organisms safety certificates for 192 plant varieties, including 189 cotton varieties, 2 corn varieties and 1 soybean variety. According to the eye information, Beijing Dabeinong Biotechnology Co., Ltd. is a holding subsidiary of Beijing Dabeinong Science and Technology Group Co., Ltd. (hereinafter referred to as "Dabeinong", 2385), and Ruifeng Bio is a shareholding enterprise of Yuan Longping Agricultural High-tech Co., Ltd. (hereinafter referred to as "Longping Hi-Tech", 998). Affected by this news, Dabeinong has been trading daily for 7 consecutive trading days since the list was publicized, and Longping Hi-Tech has also harvested several daily limit boards. As of the close of January 21, Dabei Nong's share price rose by 57.3%, and Longping Hi-Tech's share price rose by 48.1%. It is generally believed in the industry that the approval of the safety certificate of genetically modified crops in China will bring changes to the seed industry. TF Securities's research report believes that the smooth progress of transgenic is expected to accelerate the upgrading and concentration of seed industry. First of all, transgenic will significantly increase the added value of seeds, which is expected to push up the price and profit rate of seeds; Secondly, transgenic breeding has high technical barriers and R&; D large investment will further highlight the competitive advantage of head enterprises and accelerate the promotion of industry concentration. Founder Securities Research Report shows that the proposed approval of the safety certificate of insect-resistant and glyphosate-resistant transgenic corn is the first time that China has made a substantial breakthrough in the important characters of transgenic corn seeds, which will play an important role in promoting the substitution of corn seeds in the future. It is expected to provide new kinetic energy for the innovation and development of corn seed industry. Once genetically modified corn is allowed to be commercialized, it will increase the price of corn seeds and bring about the expansion of the industry. At the same time, R& D investment cost and long r&; D cycle will greatly raise industry barriers, and leading enterprises will benefit first. Then, if domestic genetically modified crops can land smoothly, what is the profit space geometry? TF Securities analysts believe that the promotion of transgenic seeds in the future will bring about the improvement of seed value. Assuming that the cost per mu of seeds in China will reach 18 yuan compared with that in the United States in 216, according to the 6 million mu of corn planting area in China, the total size of the terminal market will be 64.8 billion, the ex-factory market will be 5%, and the future corn seed market will be 32.4 billion. Monsanto's gross profit margin of corn seeds is about 65%, and its net profit margin is over 3%. Suppose that the net profit rate of genetically modified seeds in China will be 3% in the future, and the industry profit rate will be 9.7 billion yuan. If the market share of the head enterprise reaches 3%, it will realize income of 9.7 billion yuan and net profit of 2.9 billion yuan. The commercialization of genetically modified seeds will bring high income and profits to related enterprises. How far is it from industrialization? It is understood that the Ministry of Agriculture and Rural Affairs has strict procedures for issuing safety certificates for genetically modified organisms, including experimental research, intermediate tests, environmental release, productive tests and application for safety certificates. Distinguished professor Bouwing Lo, School of Life Sciences, Fudan University, said in an interview with this newspaper (www.thepaper.cn) that all the above genetically modified varieties have passed the molecular characteristics test, food safety test and environmental safety test, and the related technologies are mature and safe. However, after obtaining the biosafety certificate, the domestic transgenic varieties are still far from commercial large-scale planting, and it is still difficult to verify the varieties. According to the Regulations on the Safety Management of Agricultural Genetically Modified Organisms, after obtaining the biosafety certificate, genetically modified varieties need to pass the variety examination and obtain the seed production and operation license before they can enter the commercial production and application. Under normal procedures, the market access review period is about 1 to 2 years. So far, only cotton and papaya have been approved for commercial planting in China, and the genetically modified varieties approved for import include soybean, corn, rape, cotton and beet. However, imported genetically modified varieties can only be used as processing raw materials and are not allowed to be planted in China. In 29, the Ministry of Agriculture issued safety certificates to domestic transgenic phytase corn BVLA4311 and transgenic insect-resistant rice Huahui No.1 and Bt Shanyou 63, but they all stopped at the stage of variety approval and did not put into commercial production. Dabeinong also mentioned in the announcement that the safety certificate (production and application) of agricultural genetically modified organisms issued this time can be used for agricultural production and agricultural product processing. The company will work with partners to prepare for the industrialization of excellent corn varieties with DBN9936 characteristics, and create conditions for listing, sales and production promotion. According to the relevant laws and regulations, the approval, production, management and processing of genetically modified corn seeds need to obtain the administrative license granted by the relevant agricultural administrative departments, and the specific measures are still being worked out. Although the relevant policies are not yet clear, the industry generally believes that the industrialization of genetically modified crops in China has a bright future. The "Thirteenth Five-Year" National Science and Technology Innovation Plan clearly stated: "Promote the industrialization of major products such as new insect-resistant cotton, insect-resistant corn and herbicide-resistant soybean". The plan of the Ministry of Agriculture is to develop non-edible cash crops, feed crops, processed raw materials crops and edible crops. Genetically modified soybeans and corn are mainly used to process finished products such as edible oil and animal feed. , in the second step of the route.
