Core Insights - The research team led by academician Gui Jianfang from the Chinese Academy of Sciences has developed a breeding technology system that creates a new candidate variety of silver crucian carp with high yield, disease resistance, and feed efficiency, while also eliminating the presence of small intermuscular bones [1][2] - The new variety, referred to as "Zhongke No. 6," shows significant improvements in growth rate, survival rate in aquaculture, and feed utilization, marking a shift towards a more predictable and programmable breeding era in China's agricultural sector [1] Group 1 - The innovative breeding technology utilizes "molecular scissors" to edit the genetic code responsible for the growth of intermuscular bones, significantly reducing their occurrence [1] - The breeding system produces sterile fish, which prevents them from reproducing in natural environments, thereby considering ecological safety [1] - The advancements are part of a six-year systematic effort under the Chinese Academy of Sciences' A-class pilot project focused on "precise design and creation of seeds," indicating a transition in agricultural breeding practices [1] Group 2 - The goal of this "precise design" innovation is to enhance national food security and agricultural modernization, providing a strong foundation for China's agricultural development [2]
