Transgenic maize varieties include Zhongyu 999, Zhongyu 335, Zhongyu 68, Huayu 11, Huacheng 835, Huacheng 823, Denghai 688, Derun 91, Derun 92, Derun 93, Derun 94, Derun 95 and Derun 96.

Transgenic maize is to introduce excellent gene fragments from other plants or organisms into maize genes through transgenic technology, thus giving maize new characteristics and traits. This kind of transgenic corn has the advantages of insect resistance, disease resistance, high quality and high yield, and beautiful appearance, and is an important achievement in the field of modern agriculture.

Compared with traditional breeding methods, transgenic corn has higher genetic stability and abundant resources, which can rapidly improve corn varieties and improve the yield and quality of crops. At present, genetically modified corn is widely used in planting, which brings farmers the benefits of bumper harvest.

approval procedures

It should be noted that the promotion and planting of genetically modified corn varieties need to go through strict examination and approval procedures to ensure the safety and sustainability of genetically modified corn. In China, the research and popularization of transgenic corn started late, but some achievements have been made. Zhongyu 999 is a transgenic corn developed by Monsanto Biotechnology Company in the United States, which is endowed with the characteristics of glyphosate herbicide resistance through transgenic technology.

this variety is widely used in the world, with high insect and grass resistance and good commercial performance. Zhongyu 335 is also a genetically modified corn developed by Monsanto, but its cultivation and sales have been banned in France and other countries. This variety is mainly restricted because of its possible impact and harm to the environment.
