摘要： 【目的】水稻日开花时间是影响粳稻不育系异交率及制繁种产量的重要性状。本研究旨在定位粳稻花时调控相关的QTL并对其聚合效应加以分析，明确早花时 QTL的主效位点。【方法】利用早花时粳稻保持系粳 65B（J65B）和晚花时粳稻保持系粳 139B（J139B）构建包含 221 个家系的重组自交系群体。连续 3 年调查群体花时性状，采用遗传图谱和 BSA-seq两种方法进行花时 QTL 定位分析。【结果】 利用完备区间作图法共检测到 30 个花时性状QTL，分布于 2-12 号染色体上，其中 qFT5.2、qFT5.3、qFT5.5、qFT10.2、qFT10.3 在 8 个以上环境中被同时检测到，加性效应范围 13.04-50.93，是稳定表达的主效位点；选取花时极端早和极端晚家系构建混池，利用 BSA-seq 方法在 qFT5.3、FT5.5、qFT6.2、qFT10.2 位点检测到花时关联区域；选取两种方法共同定位到的稳定表达位点进行 QTL 聚合分析，J65B类型的 QTLs 均会提早花时，qFT5.3 和 qFT6.2 是早花时改良的基础位点，qFT5.5、qFT10.2是进一步提早花时的重要位点。【结论】采用两种方法定位到 4 个稳定表达主效花时 QTLqFT5.3、qFT5.5、qFT6.2、qFT10.2，为早花时基因进一步精细定位、基因克隆和粳稻花时性状改良奠定了基础。
