Genetically modified technology, as the core of modern biotechnology, has been widely used in agriculture, medicine, environmental protection and other fields. Especially in the field of agriculture, the research and application of genetically modified corn is particularly eye-catching. As one of the world's largest corn producers, China is also increasingly strengthening research and application of genetically modified corn. In this paper, we will introduce the main varieties and distribution of transgenic maize in China.
1. Varieties of genetically modified corn.
BT-176: This is China's first genetically modified corn variety and one of the most widely used insect-resistant corn varieties in the world. It is resistant to lepidopteran pests and resistant to glufosinate-ammonium herbicides, significantly reducing the use of pesticides and reducing environmental pollution. At the same time, the yield and quality of BT-176 corn have improved, making it suitable for large-scale planting.
NK603: This is a genetically modified corn variety developed by Monsanto that is resistant to lepidopteran pests and resistant to roundup herbicides. Since the 90s, China began to introduce NK603 corn and planted it on a large scale. This variety has high yields and strong adaptability, making it suitable for cultivation in different climatic conditions.
BVLA430101: This is a transgenic corn variety declared by the Chinese Academy of Sciences, which has pest-resistant characteristics, can reduce the use of pesticides and reduce environmental pollution. At the same time, the yield and quality have improved, making it suitable for large-scale cultivation.
In addition, China has also developed other genetically modified maize varieties, such as Jinqing 707 709 129 168, Shibin 338, Fueryume 116 216, Pengcheng 8 5 Hongchen 788, Nongda 81 77 60 50 21 108, Yuyu 22, Aoyu 3804 1, Deka 1 3, Tayu 1, Yuanfa 815, Qiaojing 607 and Zhongnongda 4.
2. Regional distribution of genetically modified maize.
Northeast and Northwest China: The genetically modified maize varieties grown in these areas include Nongda 81, Nongda 77, Nongda 60, Nongda 50, Nongda 21, Yuyu 22, Aoyu 3804, etc.
Central and East China: The genetically modified maize varieties grown in these areas include Zhongyu 999, Zhongyu 335, Zhongyu 608, Huayu 11, Huacheng 835, Huacheng 823, Denghai 688, etc.
In conclusion, China has made remarkable achievements in the research and application of genetically modified maize. The large-scale planting of multiple transgenic maize varieties proved that it had good ecological, social and economic benefits. However, with the continuous progress of technology and the continuous change of market demand, we need to continue to strengthen R&D and management to promote the healthy development of China's genetically modified corn industry.
