摘　　要：倒伏性是大豆高产、稳产和优质的主要限制因子之一,是控制大豆产量性状的主要数量性状。本研究共搜集整理了16年来已经报道的与大豆倒伏性有关的59个QTL,以2004年发布的大豆公共遗传连锁图谱soymap2为参考图谱,通过软件BioMercator2.1的映射,将大豆倒伏性QTL整合到soymap2上,并利用Meta进行元分析进而推断QTL位置,计算提取真正有效的QTL位点,共得到11个与大豆倒伏性相关的真实主效QTL位点,分布于5个连锁群上。本研究结果为倒伏性相关基因的精细定位和克隆奠定了基础。Lodging is one of the main limit factors for high and stable yield and good quality of soybean,which is a quantitative trait.In this research,59 QTLs,reported in recent 16 years related with soybean lodgingw collected.An integrated map of soybean lodging QTLs had been established with soymap2,published in 2004,as the reference map.With the software BioMercator2.1,QTLs were projected from their own maps to the reference map.A method of meta-analysis was used to narrow down the confidence interval,11 consensus QTLs and their corresponding markers were obtained respectively.The results would be the basis for fine mapping and cloning of genes for lodging in soybean.
