没有小刺的鲫鱼、水稻明星品种，中国科学院种子专项成果发布

Core Insights - The Chinese Academy of Sciences has launched a seed precision design initiative, achieving significant agricultural advancements over six years, including the creation of 37 "increase and decrease" pilot varieties and the promotion of 14.48 million acres of new crop varieties, resulting in notable socio-economic benefits [1][2]. Group 1: Agricultural Innovations - The seed initiative aims to address challenges in sustainable agriculture, focusing on increasing crop yield and quality while reducing fertilizer and pesticide usage by 15% to 20% and minimizing losses from natural disasters by the same percentage [2][3]. - Key breakthroughs include the cloning of the nitrogen-efficient gene OsTCP19, allowing rice to maintain stable yields while reducing nitrogen fertilizer by 20% to 30%, contributing to a "green revolution" in rice production [3][4]. - The initiative has also developed a high-yield wheat variety "Zhongke 166" that is resistant to major diseases, significantly reducing pesticide usage and covering nearly 1.5 million acres [4]. Group 2: Advanced Breeding Techniques - The project has transformed traditional breeding methods into a precise science, utilizing genome editing technologies to create disease-resistant and high-yield crop varieties [5][6]. - A new approach to rapid domestication of wild rice has been established, shortening the domestication process from thousands of years to just a few years [6]. - The "Zhongke Fa" series of rice has become a star variety, with significant yield improvements over local varieties, and has introduced early-maturing rice options to the market [7]. Group 3: Future Directions - The initiative emphasizes the importance of establishing an independent and leading scientific system in seed technology, aiming to develop smarter seeds that are higher yielding, more nutritious, and resilient to disasters, contributing to global food security and sustainable agriculture [8].
