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].
