中新网天津9月15日电 (记者 王君妍)记者14日从天津海关获悉，天津邮局海关近日在出境邮递渠道截获 1票寄往境外的植物种子共3包1306克，经天津市农作物种质资源库鉴定，为《农作物种质资源清单目 录》所列监管品种，系天津口岸首起违规邮寄种质资源出境情事。目前涉案种质资源已移交相关部门依 法处置。 据了解，今年前8个月，天津海关共累计在出境邮递渠道查获农作物种子7批次、86份，经鉴定均为《农 作物种质资源清单目录》所列监管品种。 今年9月23日为第八个"中国农民丰收节"。近年来，为加强种子种质资源保护，筑牢国门生物安全防 线，天津海关在机检环节强化风险分析，结合查获夹藏情况形成种子资源监管典型机检图像库，为机检 审像快速判图提供指引；在口岸查缉环节，以"断链刨根阻源"为目标开展专项行动，加大对可疑邮件的 人工查验力度，强化对于走私种子资源出境行为的预防和打击效能。此外，天津海关还积极与种子资源 监管相关部门优化沟通联系机制，在实物移交、种质鉴定、专业支撑等方面加强配合，不断形成监管合 力。 根据新修订的《中华人民共和国种子法》第十一条第一款：国家对种质资源享有主权。任何单位和个人 向境外提供种质资源，或者与境 ...

Core Viewpoint - The article highlights the establishment and advancements of the National Crop Germplasm Resource Bank in China, emphasizing its role in preserving agricultural biodiversity and enhancing seed quality through modern technologies [2][5]. Group 1: Germplasm Resource Preservation - The National Crop Germplasm Resource Bank serves as a "Noah's Ark" for crop genetic resources, crucial for developing new crop varieties and combating extinction risks due to climate change and human activities [2][3]. - The new facility, built in 2021, has a storage capacity of 1.5 million samples, significantly increasing from the previous capacity of 400,000 samples [3][4]. - Recent efforts have led to the collection of unique germplasm, such as high-altitude barley from Tibet and rare corn varieties, which are essential for breeding programs [3][4]. Group 2: Technological Advancements - The new resource bank employs advanced technologies for seed quality assessment, including CT scanning and non-destructive testing methods, improving efficiency and reducing seed consumption during testing [4]. - The facility includes specialized storage options like tissue culture and ultra-low temperature storage, allowing for tailored preservation methods for different types of crops [4]. - Automation in the storage process has increased efficiency, with robotic systems handling seed storage and retrieval, thus optimizing space and reducing labor costs [4][5]. Group 3: National Strategy and Future Prospects - The establishment of the resource bank is part of a broader national strategy to enhance the protection and utilization of agricultural genetic resources, including crops, livestock, and aquatic species [5]. - The identification of genetic and phenotypic traits of preserved resources exceeds 60% and 30%, respectively, providing a foundation for future AI-driven breeding innovations [5]. - An information platform for crop germplasm resources is set to launch, facilitating better resource sharing and collaboration [5].
