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

important staple crop, yet increasing climatic variability and abiotic stresses threaten yield stability and food security. Accelerating the genetic dissection of yield-related traits is therefore critical for developing climate-resilient rice cultivars. Methods In this study, we characterized the genetic diversity and genomic architecture of agronomically important traits in 188 advanced breeding lines (ABLs) developed at IGKV, India. Results and discussion We genotyped the ABLs using genotyping-bysequencing, and identified 87 high-quality, trait-informative single-nucleotide polymorphism markers distributed across all 12 rice chromosomes. STRUCTURE analysis revealed five genetically differentiated subgroups (SG1–SG5), comprising 59, 31, 36, 44, and 18 accessions, respectively, indicating substantial genetic stratification. Eight yield-associated agronomic traits were phenotypically evaluated and subjected them to genome-wide association analysis. In total, 34 marker– trait associations (MTAs) were detected, each explaining 2.00%–11.05% of phenotypic variance, consistent with a polygenic architecture. A notable QTL hotspot on chromosome 6 was identified, representing a promising genomic region for simultaneous improvement of multiple traits. Integrating population structure, genome-wide markers, and phenotypic data provides a robust framework for exploiting favorable alleles in Central Indian rice germplasm. These MTAs and the chromosome 6 hotspot warrant validation and may support marker-assisted, genomic selection, and genomics-assisted breeding for high-yielding, climate resilient rice cultivars.","引言 水稻是重要的主粮作物，但日益加剧的气候变率和非生物胁迫威胁着产量稳定性和粮食安全。因此，加快产量相关性状的遗传解析对于培育气候韧性水稻品种至关重要。方法 本研究对印度IGKV开发的188个高级育种品系（advanced breeding lines，ABLs）的农艺重要性状进行了遗传多样性和基因组结构表征。结果与讨论 我们采用测序基因分型（genotyping-by-sequencing）对ABLs进行基因分型，鉴定出87个高质量、性状信息丰富的单核苷酸多态性标记，分布于全部12条水稻染色体上。STRUCTURE分析揭示了5个遗传分化亚群（SG1–SG5），分别包含59、31、36、44和18份材料，表明存在显著的遗传分层。对8个产量相关农艺性状进行了表型评价，并进行了全基因组关联分析。共检测到34个标记–性状关联（marker–trait associations，MTAs），每个关联解释2.00%–11.05%的表型变异，符合多基因结构。在第6号染色体上鉴定到一个显著的QTL热点，代表了一个有望同时改良多个性状的基因组区域。整合群体结构、全基因组标记和表型数据，为挖掘印度中部水稻种质中的有利等位基因提供了稳健框架。这些MTAs和第6号染色体热点值得进一步验证，并可能支持标记辅助选择、基因组选择和基因组学辅助育种，以培育高产、气候韧性的水稻品种。","Frontiers in Sustainable Food Systems","论文",78,{"impact":45,"substance":17,"depth":117,"authority":202,"freshness":12,"relevant":21,"comment":277},"印度水稻育种系GWAS研究，方法规范、数据扎实，对分子育种有参考价值，但属区域性科研进展，公共影响有限。",[279],{"name":273,"url":270},[26,27,281,282,283],"气候韧性农业","全基因组关联分析","分子标记辅助育种",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[],{"status":38,"locked":39,"version":40,"method":41,"evidence":287},{"candidates":288,"agricultural_evidence":13},[289,293,298,304,310],{"code":31,"score":45,"supported":13,"title":290,"abstract":291,"tags":292},[32],[33,32],[27],{"code":93,"score":62,"supported":13,"title":294,"abstract":295,"tags":297},[],[79,296],"food security",[],{"code":172,"score":62,"supported":13,"title":299,"abstract":300,"tags":303},[],[301,302],"基因组选择","genomic selection",[],{"code":51,"score":305,"supported":13,"title":306,"abstract":307,"tags":309},4,[],[308],"germplasm",[26],{"code":311,"score":21,"supported":39,"title":312,"abstract":313,"tags":314},"H7",[],[],[281],[316,317],"IGKV 水稻 育种系","水稻 染色体6 QTL","IGKV水稻育种系-4789","10.3389\u002Ffsufs.2026.1981880",{"doi":319,"openalex_id":321,"authors":322,"venue":273,"cited_by_count":106,"oa_url":270,"card":354,"direction":358,"ingested_from":360},"W7221562552",[323,326,329,331,334,337,340,342,345,347,350,352],{"name":324,"orcid":325},"Abhinav Sao","https:\u002F\u002Forcid.org\u002F0000-0003-1855-4688",{"name":327,"orcid":328},"Sunil Kumar Nair","https:\u002F\u002Forcid.org\u002F0000-0003-1662-9439",{"name":330,"orcid":8},"Deepak Gauraha",{"name":332,"orcid":333},"Hemant Sahu","https:\u002F\u002Forcid.org\u002F0009-0002-0017-0790",{"name":335,"orcid":336},"Saurabh Pandey","https:\u002F\u002Forcid.org\u002F0000-0002-9142-1788",{"name":338,"orcid":339},"Tarun Kumar Thakur","https:\u002F\u002Forcid.org\u002F0000-0001-9389-1292",{"name":341,"orcid":8},"Prafull Kumar",{"name":343,"orcid":344},"Ritu R.
