Core Viewpoint - The speech emphasizes the importance of hybrid wheat in enhancing food security and agricultural productivity, highlighting the need for innovative breeding techniques to overcome existing limitations in hybrid wheat production [3][4][5]. Group 1: Importance of Hybrid Wheat - Wheat is crucial for global food security, with over one-third of the world's population relying on it for sustenance [3][4]. - The application of hybrid varieties has significantly increased yields in crops like corn, achieving at least a sixfold increase in yield per unit area [3][4]. - Despite the success of hybrid corn (100% adoption) and rice (50% adoption), hybrid wheat remains underutilized, with less than 1% adoption in both China and internationally [3][4][5]. Group 2: Challenges in Hybrid Wheat Breeding - The production of hybrid wheat faces significant challenges due to the self-pollinating nature of wheat, which complicates the creation of hybrid varieties [4][5][6]. - Traditional methods for producing male-sterile lines in wheat have proven inadequate, leading to low-quality hybrid wheat production [6][8]. - The discovery of male sterility genes has been pivotal, with historical successes in hybrid rice breeding serving as a model for potential advancements in hybrid wheat [5][6][7]. Group 3: Innovations in Hybrid Wheat Technology - The development of new breeding technologies, such as the CASP (Chromosome Assisted Seed Production) technique, aims to produce high-quality male-sterile lines for hybrid wheat [9][10]. - The introduction of the Msg47 gene, which ensures the purity of male-sterile lines, represents a significant advancement in hybrid wheat breeding [9][10]. - The ByF1 technology, which allows for high-throughput and efficient breeding, has been implemented to identify superior parent combinations for hybrid wheat [11][12]. Group 4: Future Prospects and Economic Impact - The potential for hybrid wheat to significantly increase grain production is substantial, with estimates suggesting a possible increase of 273 billion jin (approximately 136.5 million tons) in grain output [16][34]. - The commercialization of hybrid wheat could transform the seed industry, potentially increasing its market value from 16 billion yuan to 35 billion yuan [16][34]. - The global market for hybrid wheat is expected to expand, with major international companies planning to introduce new hybrid wheat varieties by 2027 [16][34].

中国科学院分子植物科学卓越创新中心研究员林鸿宣团队与上海交通大学研究员林尤舜团队等合 作，破解了水稻感知并响应高温的双重"密码锁"，揭示了植物中的一个循序激活、协同串联的热信号感 知响应机制，成功培育出具有梯度耐热性的水稻新株系。该成果不仅为耐高温分子育种提供了有力支 持，更为应对全球变暖导致的粮食减产提供了新的解决方案。相关研究成果日前发表于国际学术期刊 《细胞》。 该机制的破解为作物育种提供了精准靶点。据悉，全球平均气温每升高1℃，作物将减产3%— 8%，小麦、玉米、水稻和大豆四大作物减产合计达19.7%。研究团队基于DGK7和MdPDE1开展遗传设 计，在模拟高温的田间试验中取得喜人结果：单基因改良的水稻株系比对照株系增产50%—60%；而水 稻耐高温基因TT2协同DGK7的双基因改良株系比对照株系产量提升约一倍，且米质更优。 "这意味着，未来科学家不仅能增强作物的耐热性，更能像调节音量一样精准设计'梯度耐热'品 种，以适应不同地区的气候需求，维持作物在高温环境下的产量稳定。"中国科学院院士、中国科学院 分子植物科学卓越创新中心主任韩斌说。 （原载于《科技日报》 2025-12-22 08版） 进入灌浆 ...
