立秋刚过，山东乐陵寨头堡乡冢上村，玉米正值授粉期，乐义农作物种植专业合作社负责人闫乐义一大 早就在地里查看玉米长势、密度，了解抽雄授粉出穗等情况。 新华社记者古一平、胡璐 "这个品种耐盐碱、耐干旱，抗病抗倒伏能力强，虫害也不多，看样子今年也能有个好收成。"闫乐义告 诉记者，他从2021年起开始种植玉米新品种"中玉303"，这几年每亩地产量比以往多出三四百斤。 种子是农业的"芯片"。近年来，为更好满足持续增长的市场需求，我国重要农作物玉米涌现出越来越多 高产耐密植、优质宜机收新品种，生动展现了我国种业创新发展的坚实步伐。 国家玉米育种联合攻关秘书长、中国农业科学院作物科学研究所研究员王天宇告诉记者，曾几何时，我 国玉米"过硬"品种不多，加之近年异常气候频发，产量提升不稳定，经常受高温干旱等因素困扰。同时 玉米茎腐病和穗粒腐病等玉米的"癌症"也是厉害的"杀手"，直接影响到玉米产量和质量。 新华社北京8月13日电 题：解锁"芯片"密码 我国种业创新迈出坚实步伐 "努力攻关研究出耐盐碱、抗洪耐旱的玉米品种，解决农业生产实际问题，迫在眉睫。"他说。 与水稻、小麦等不同，玉米起源于美洲，我国玉米种质资源并不丰富，并且种植 ...

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].
