The reporter learned from the Chinese Academy of Sciences on the 22nd that Gui Jianfang's team, an Academician of the Chinese Academy of Sciences and a researcher at the Institute of Hydrobiology of the Chinese Academy of Sciences, has cultivated new heterozygous silver crucian carp candidate varieties with the three major advantages of high yield, disease resistance, and food saving, and heterozygous silver carp that is “devoid of intermuscular spines” and is sterile. Although crucian carp has tender meat and is rich in nutrients, it has as many as 80 tiny intermuscular spurs in its body, which discourages many people. Researchers in China use “molecular scissors” to accurately find the key “code” that controls the growth of intermuscular spurs and edit them, significantly reducing the generation of small spines at the source of life. At the same time, silver crucian carp cultivated through this system is controllable and sterile. It is like installing a “biosafety lock” to prevent it from growing in the natural environment, taking full account of ecological safety. Relying on this technology, the “Zhongke No. 6” candidate new breed has achieved significant improvements in growth rate, survival rate, and feed utilization rate, and has excellent overall performance. Fu Xiangdong, an Academician of the Chinese Academy of Sciences and deputy director of the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, said that in the future, we will not only be able to enjoy delicious food with more peace of mind, but also obtain better quality protein with fewer resources and higher efficiency. This series of breakthroughs stemmed from a six-year systematic research project “Precise Seed Design and Creation”, a Class A pilot project of the Chinese Academy of Sciences, marking that agricultural breeding in China is fully moving from “watching the sky and selecting” to an era of predictable and programmable “precise design”. As Li Jiayang, chief scientist of the project and an Academician of the Chinese Academy of Sciences, said, the goal of this “precise design” innovation is to create a “Chinese core” with strong impetus for the country's food security and agricultural modernization.
