银杏濒危？保护种质资源不止是保护种子

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]
