Core Viewpoint - The establishment of the National Crop Germplasm Resource Bank represents a significant advancement in the preservation of agricultural genetic resources, ensuring the protection and utilization of valuable genetic materials amid threats from climate change and human activities [3][15]. Group 1: Germplasm Resource Preservation - The National Crop Germplasm Resource Bank serves as a "Noah's Ark" for safeguarding crop genetic resources, which are crucial for future agricultural innovations [3][19]. - The new facility, completed in 2021, has a storage capacity of 1.5 million samples, significantly increasing from the previous capacity of 400,000 samples [6][15]. - The bank is actively collecting and preserving new genetic resources, including rare and unique varieties identified during the largest agricultural germplasm survey in China's history [7][19]. Group 2: Technological Advancements - The new facility employs modern technologies for seed quality assessment, including CT scanning and non-destructive testing methods, enhancing efficiency and reducing seed consumption during testing [11][12]. - The introduction of specialized storage solutions, such as ultra-low temperature and tissue culture facilities, allows for the preservation of plant materials that cannot withstand traditional seed storage conditions [12][14]. - Automation in the storage process has improved operational efficiency, reducing the need for manual labor and optimizing space utilization within the facility [13][14]. Group 3: National Strategy and Future Prospects - The establishment of the National Crop Germplasm Resource Bank is part of a broader national strategy to enhance the protection of agricultural genetic resources, including livestock and aquatic species [16][18]. - The current identification rates for genotypes and phenotypes exceed 60% and 30%, respectively, providing a substantial data foundation for future AI-driven breeding innovations [17]. - The upcoming launch of a national crop germplasm resource information platform will facilitate better sharing and exchange of genetic resources [17].
