摘    要:利用黄瓜远缘群体的分子遗传连锁图谱,对雌花节位性状进行了QTL定位。共找到8个控制雌花节位的QTL位点:ff-1、ff-2、ff-3、ff-4、ff-5、ff-6、ff-7、ff-8,分别位于LG2、LG3、LG6、LG7连锁群上,这些QTL位点对雌花节位性状表型变异贡献率分别为81.6%、81.0%、81.0%、80.0%、80.6%、81.1%、81.0%、80.7%,其中ff-1、ff-2、ff-5、ff-6、ff-7、ff-8加性效应值为正,为增效加性效应,ff-3、ff-4加性效应值为负,是减效加性效应。

关 键 词:黄瓜  QTL定位  始花节位

Abstract:QTLs mapping of firse female flower node was conducted by using genetic linkage map derived from population with distinct parents of cucumber. Total 8 QTLs,ff1-8,were found on the map,locating on the linkage group 2,group 3, group 6 and group 7,respectively. The percentages of variation explained for the phenotype are 81.6% ,81.0%,81.0%, 80.0%,80.6%,81.1%,81.0% and 80.7%,respectively. All of the 8 QTLs showed positive additive effect except ff3,ff4 loci that showed negative additive effect.
Keywords:Cucumber(Cucumis sativus L.)  QTL location  First female flower node
