金秋时节，稻浪飘香。近日，全省籼粳杂交稻新品种现场观摩会在海盐召开，现场展示了43个籼粳交水稻品种，其中对8个优势籼粳杂交稻品种、7个籼粳杂交稻新品种进行了集中推介。\n\n活动集中展示了43个籼粳杂交水稻品种。经专家现场测产、性状评估，浙粳优1578、华中优9326、浙禾优127等8个丰产性好、综合性状优良的籼粳杂交水稻品种被重点推介。目前，这些品种已在省内外大规模推广种植。\n\n“种子就是粮食生产的‘芯片’。籼粳杂交品种的推出，能为我们大面积单产提升打下很好的品种底子，因为品种才是核心。籼粳杂交品种需要具备一定的综合抗性，比如抗病、抗虫，因为各地区的实际情况不同。所以这类品种的推广，能为大面积单产提升提供扎实的基础。”中国水稻研究所副研究员王亚梁表示。\n\n承担此次新品种种植的海盐示范基地，位于通元云飞农场。在该示范基地，记者看到籼粳杂交稻品种“浙禾优127”稻穗饱满、色泽青中泛黄，已处于成熟期。基地工作人员表示，该品种具有丰产性好、抗倒伏性强等突出优势。\n\n近年来，海盐加强农业科技创新推广力度，围绕“绿色、低碳、科技、示范”等要求，通过新品种、新技术的集中应用展示，使基地成为推广应用农业科技新成果的示范基地、技术超市和田间学校。\n\n“我们试种测产后，这款水稻亩产达到920斤，今年的长势依旧很好。”浙江省农作物新品种展示示范基地负责人、云飞农场负责人孙飞介绍，“这个品种有抗倒伏、耐高温的优点，长势挺拔，结实率高。一般的稻子亩产达到这么高时很容易倒伏，它就不会，农户就喜欢这种。”\n\n据了解，浙禾优系列品种由浙江勿忘农种业股份有限公司培育。“浙禾优系列是抗病性很好的水稻品种，不同地区的试种结果表明，今年白叶枯病比较严重，浙禾优在抗病性、尤其是抗白叶枯病方面表现特别突出。”浙江勿忘农种业股份有限公司水稻种业部经理湛立伟表示。\n\n目前，全省水稻种植面积约1000万亩，其中籼粳杂交稻种植面积超过50%。过硬的育种实力，为全省乃至全国粮食单产提升提供了有力支撑。此次活动不仅集中展示了长江中下游稻区在水稻育种创新领域的实力与成果，还通过深化产学研协同，为推进水稻种业高质量发展提供了重要平台。\n\n“浙江省的稻作技术，包括品种技术和栽培技术，在全国是领先的。比如我们的籼粳交品种，已经发展了接近20多年，这点就很厉害。”王亚梁表示，“下一步，要突出两个方向：优质稻优质、高产。以前都说先高产、后优质，现在要倒过来，优质的同时要实现高产。所以这两条是平行的——高产优质、优质高产，要协同发展，实现水稻大面积提产增效。”","海盐县人民政府

tolerance in rice\n\nHuimin Shi, Kuitian Shao, Zhihu Ding, Jian Feng, Zhiyuan Zhang, Huimin Cao, Wenyu Zhang, Xiuqin Zhao, Tianqing Zheng, Dapu Liu, Kai Chen, Wensheng Wang, Fan Zhang, Jianlong

Identifying major cold-tolerance genes and deciphering their regulatory networks is therefore essential for rice molecular breeding for cold tolerance. Here, through a genome-wide association study (GWAS) in a multi-parent advanced generation intercross (MAGIC) population, we identified _OsNHX2_, a tonoplast-localized K+ transporter that enhances cold tolerance at the seedling stage. OsNHX2 enhances cold tolerance by promoting an increase in potassium ion content in shoots, which stimulates proline accumulation and reduces the levels of reactive oxygen species (ROS) and malondialdehyde (MDA). Natural variation in the coding region of _OsNHX2_ underlies differences in K+ transport ability. We further demonstrated that _OsNHX2_ expression is negatively regulated by the transcription factor OsATH1. One natural variant in the _OsNHX2_ promoter, a 45-bp deletion, elevates _OsNHX2_ expression by reducing OsATH1 binding. Notably, we found that OsNHX2 physically interacts with OsGAPC3, a cytosolic glyceraldehyde-3-phosphate dehydrogenase known to modulate responses to abiotic stresses via ROS signaling. This interaction masks the tonoplast-targeting signal of OsNHX2, altering its subcellular localization, impairing K+ transport, and promoting cytosolic K+ accumulation. Overexpression of _OsNHX2_ significantly increased the seed-setting rate under cold stress at the booting stage without compromising grain yield under normal conditions. Haplotype analysis revealed that rice accessions carrying the cold-tolerant _OsNHX2_ haplotype are predominantly distributed in higher-latitude regions, suggesting adaptive selection. Our findings demonstrate that OsNHX2, which is negatively regulated by OsATH1 and OsGAPC3 at both transcriptional and post-transcriptional levels, modulates intracellular K+ accumulation to control cold tolerance in rice.","中国农业科学院作物科学研究所 2026 年 10 月 14 日","2026-10-14T00:00:00Z",90,{"impact":17,"substance":94,"depth":278,"authority":19,"freshness":12,"relevant":21,"comment":279},19,"国家级科研机构在顶刊发表的水稻耐寒关键基因机制研究，方法新颖、结论可靠，对耐冷分子育种具有直接指导价值。",[281],{"name":274,"url":271},[26,283,284,28,285],"分子育种","水稻耐寒","作物科学",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[],{"status":38,"locked":39,"version":40,"method":41,"evidence":289},{"candidates":290,"agricultural_evidence":13},[291,296,300],{"code":31,"score":292,"supported":13,"title":293,"abstract":294,"tags":295},11,[33],[33],[],{"code":55,"score":174,"supported":13,"title":297,"abstract":298,"tags":299},[],[283],[283,28],{"code":50,"score":21,"supported":39,"title":301,"abstract":302,"tags":303},[],[],[26],[305,306],"中国农科院作科所 OsNHX2 水稻耐寒","OsNHX2 钾离子转运 耐冷育种","中国农科院作科所OsNHX2水稻耐寒-4936","2026-10-15T00:06:01.809568Z"]
