摘要
以 4 8 2× 5 0 0 3的 16 6个F2 :3家系作为定位群体 ,采用 13× 13α 简单格子方设计 ,在成都、雅安分别调查了株高、穗位高、穗长、秃尖长、穗行数、行粒数、穗粗、轴粗、粒深、30 0粒重、出籽率、小区产量等 12个经济性状 ,采用区间作图法对其进行QTL定位分析 ,共检测出 5 9个QTL ,每个性状检测出 3~ 8个QTL ,单个QTL的作用可解释表型变异的 8 4 %~4 2 2 % ,每一性状的QTL可解释表型变异的 19 5 %~ 70 9%。 5 9个QTL分布于 10个连锁群的 33个标记区域 ,其中第 1、3连锁群较多 ,分别占 2 4 2 %、15 2 % ;33个标记区域中 19个区域作用单一性状 ,6个区域分别作用两个性状 ,4个标记区域 (bnlg10 83、bnlg10 35、bnl8 4 5a、csu16 )分别作用于 3个性状 ,3个标记区域 (csu9、phi0 5 3、phi0 2 2 )分别作用于 4个性状 ,nc0 12区域同时作用于 5个性状。
