摘要
在构建 DH群体 RFLP图谱的基础上定位了产量因子的数量性状位点 (QTL) .在杭州和海南两地分别种植包括 12 3个 DH原的 DH群体及其亲本 IR6 4和 Azucena,并对产量因子性状进行了测定 .运用调整无偏预测 (AUP)法预测遗传主效应值和 GE互作效应值 ,并用于 QTL定位 .结果表明 ,一些有主效应的 QTL同时具有 QTL×环境 (QE)互作效应 ,而一些没有主效应的 QTL也可以有 QE互作效应 .研究还表明 ,QTL对环境的敏感性不同 ,有的 QTL只能在一个环境中检测到 ,而另一些 QTL能在二个环境中都检测到 .产量因子包括总粒数和实粒数的 QTL无论是主效还是 QE互作效应均具有较大的加性效应值 ,这些 QTL在两个环境中起主基因的作用 .
