Core Viewpoint - The article highlights the advancements in seed breeding technology at the Hefei Intelligent Breeding Accelerator, showcasing how innovative methods can significantly reduce the time required to develop new crop varieties from ten years to as little as two years, thereby enhancing agricultural productivity and sustainability [5][9]. Group 1: Breeding Technology Evolution - Traditional seed selection methods, referred to as "Breeding 1.0," have been practiced for thousands of years, focusing on selecting visually appealing and robust seeds [5]. - The introduction of hybrid breeding techniques marked the transition to "Breeding 2.0," which allowed for the cross-breeding of plants but faced limitations due to the scarcity of superior parent plants [6]. - The development of molecular breeding techniques, known as "Breeding 3.0," has improved the efficiency of seed evolution through genetic marking and tracking [6]. Group 2: Intelligent Breeding 4.0 - The Hefei Intelligent Breeding Accelerator represents the "Breeding 4.0" era, utilizing biotechnology and information technology to enhance seed development processes [6]. - The facility employs three key chambers: the Ion Chamber for mutation breeding, the Adversity Chamber for stress testing, and the Generation Acceleration Chamber for rapid seed propagation [7][8]. - The Ion Chamber has successfully created over 4,000 unique germplasm resources, including the notable "Crisp-stalk" rice variety, which is designed to be resilient and beneficial for soil health [7]. Group 3: Advanced Testing and Future Directions - The Adversity Chamber simulates extreme weather conditions to identify superior seed traits, allowing for the selection of the best-performing plants under stress [8]. - The Generation Acceleration Chamber can produce six generations of crops in one year, significantly speeding up the breeding cycle [8]. - The facility also features an Intelligent Breeding Center equipped with advanced scanning technology to assess seed vitality and quality, with future plans to integrate AI for more precise breeding strategies [8].
