The larvae of the aphids that injurious to the rice had been bred by Zhejiang University a few days ago. Once they have eaten the stems and leaves without rice, they will die within two days. This new strain of transgenic rice resistant to aphids is called Huachi 2000B1 and Huachi 2000B6, and was jointly developed by the Institute of Nuclear Agriculture and Applied Entomology Research Institute of Zhejiang University. At the pilot site today, the reporter saw that, in the absence of pesticides, the “Jiayu 948†as a control was heavily infested, and dead leaves could be seen everywhere, but the new line of anti-fungus plants could not see the symptoms of insect pests. This is why the rice anti-aphid new strain is toxic to aphids. The key is to transfer a resistance gene. Since 1995, Zhejiang University Science and Technology personnel successfully cooperated with the University of Ottawa of Canada to successfully transfer anti-aphid genes to rice plants. In 1998, they acquired the germplasm resources of Kezidao No. 1 and No. 2 against aphids. Indica rice stably transmits and expresses resistance genes, which are highly resistant to common borer borer, rice borer borer, and vertical leaf curl. After hatchlings, the newly hatched larvae generally die in two days. . On this basis, the scientists and technicians have, through the methods of crossbreeding and backcrossing, successively bred and developed two stable early-indica rice anti-fungus new lines, Huachi 2000B1 and Huachi 2000B6. Locusts are the main pests of rice, and the country suffers an area of ​​10 million hectares per year. For a long time, locusts were mainly controlled by chemical pesticides, which not only increased the cost of rice production, but also caused environmental pollution, pesticide residues and Other issues. At today’s on-site visits and seminars, experts at home and abroad, including Academician Chen Ziyuan, highly praised Zhejiang University’s “Breeding and Research on Transgenic Rice Resistant to Transgenic Riceâ€. They believe that Zhejiang University’s research has already taken the lead in the world. Previously, Kejin had been defined as the safest grade by the Agriculture Genetically Modified Organism Safety Committee of the Ministry of Agriculture and passed food safety certification. Another study also showed that glutinous rice has no significant effect on other insects in rice fields and will not destroy ecological diversity.
