摘要：

穗粒数是小麦的重要产量性状之一,本研究以人工合成双二倍体小麦Am3为供体,普通小麦品种莱州953为受体,培育出了高穗粒数BC5F1导入系,以导入系后代75个BC5F2∶3为材料,利用复合区间作图法对其进行穗部性状的QTL定位。共检测到2个控制穗长、4个控制小穗数、2个控制穗粒数的QTL位点,贡献率分别为1%22%、1%9%和1%15%。其中穗长和穗粒数分别有1个QTL能在两年重复检测到。并且在1A染色体上检测到同时控制小穗数和穗粒数的QTL,穗长和小穗数的QTL被定位在4A染色体上同一个区域,表明这2个位点是与穗部性状有关的热点区域。本研究发现的QTL多为来自Am3的新位点,对于小麦改良将具有重要价值。
