The problem that American scientists have been eager to solve for 40 years has been solved by Zhu Dengyun of Jinhua. Zhu Dengyun, who has not returned home for three years, returned to his hometown with great news in the Spring Festival in 2004. The person in charge of the Office of GM Management of the Ministry of Agriculture told him that he was chairing the "High Protein, High Lysine GM Maize Inbred Line". The "selection of hybrid combinations" project has completed environmental release tests in the safety evaluation system and will soon be applied to production. Zhu Dengyun grew up in a peasant family in Jindong District of Jinhua. After graduating from Zhejiang University in 1984, he was admitted to the China Agricultural University in 1990 to pursue a master's degree, a doctoral degree, and a post-doctoral degree. He then taught at the postgraduate school as a “high-protein, high-lysine transgenic maize inbred lineâ€. And head of the crossbreeding group". After seven years of painstaking research, his research team turned a gene from potato pollen into corn. As a result, the content of lysine and protein was much higher than that of conventional corn, thus conquering an international problem. The planting area of ​​corn in China is more than 300 million mu, but the nutritional quality of corn is relatively poor, and the content of protein and lysine is low. Therefore, high-quality lysine and other feed additives must be added to feed to meet the growth and development of livestock and poultry. need. The use of genetically modified corn to process feeds requires only the addition of some minerals, which can reduce costs by more than 30% per ton of feed.
