Group 1 - The core issue is the distinction between wild ginkgo, which is endangered, and landscape ginkgo, which lacks genetic diversity despite being common in cities [1] - Germplasm resources are crucial for agriculture, encompassing not just seeds but also various plant parts and genetic materials, highlighting their broader significance [1] - The importance of germplasm resources is underscored as they are foundational to agricultural innovation and food security [2] Group 2 - China is a major germplasm resource country but still faces challenges in precise identification and the development of breakthrough varieties [3] - Current phenotypic identification of germplasm resources in China is only 35%, with a target of 60% by 2030, indicating a significant gap [3] - The integration of artificial intelligence in breeding innovation is essential for enhancing the breeding system and accelerating the development of new varieties [3]

Core Viewpoint - The Chinese seed industry has made significant progress over the past five years, with a focus on achieving self-reliance in seed technology and ensuring seed source security, which is now considered a matter of national security [1][2]. Group 1: Policy and Strategic Framework - The Central Economic Work Conference in December 2020 emphasized the importance of addressing seed and arable land issues, aiming to revitalize the seed industry [1]. - The "Seed Industry Revitalization Action Plan" was approved in July 2021, highlighting the commitment to seed industry revitalization, which has been included in the 20th National Congress report and the 14th Five-Year Plan [1]. - The revitalization plan outlines a timeline of "one year to start well, three years to lay a foundation, five years to see results, and ten years to achieve major breakthroughs," reflecting respect for scientific and industrial laws [1]. Group 2: Achievements and Innovations - The protection and utilization of germplasm resources have improved, with China now holding the world's largest total of preserved germplasm resources and a rising identification ratio [2]. - Over 95% of self-bred crop varieties are now domestically sourced, with domestic market shares for livestock, aquaculture, and vegetables exceeding 80%, 85%, and 91% respectively [2]. - The selection of 270 leading seed companies from over 30,000 has strengthened the competitive landscape, with companies like Syngenta and Longping High-Tech ranking among the top 10 globally [2]. Group 3: Global Competition and Future Outlook - The global seed industry is characterized by high technology, high investment, and high market concentration, with multinational corporations holding a significant share of core patents and market segments [3]. - China is working to enhance its research and development capabilities, as approximately 80% of its seed technology resources and talent are still concentrated in research institutions [3]. - The next five years are crucial for the second half of the "ten-year sword polishing," with a shift towards "smart breeding" characterized by biotechnology and artificial intelligence [3].
