摘　　要：株高是影响大豆产量的主要性状之一,本研究利用Charleston×东农594重组自交系构建的SSR遗传图谱,采用WinQTLCartographer Ver.2.5软件的CIM和MIM分析方法对2006-2008年连续3年的大豆株高数据进行QTL定位,检测到了15个控制株高的QTLs,分别位于LGB1、LGD1a和LGG等。另外,利用BioMercator2.1的映射功能将国内外常用的大豆图谱上的株高QTLs通过公共标记映射整合到大豆公共遗传连锁图谱soymap2上,将搜集到78个株高QTLs和本研究得到QTLs进行整合分析,最终得到12个大豆株高的"通用"QTL,分别位于LGB1、LGC2、LGD1a、LGF、LGG、LGK和LGM,其置信区间最小可达到0.24cM,为今后对大豆株高QTL精细定位,提供有利指导。Plant height was one of very complicated quantitative traits of soybean yield.In this study,we analyzed QTLs data of soybean height between 2006 and 2008 with a recombination inbred lines（RIL） population derived from a cross between Charleston and Dongnong 594 by mixed linear model approach.15 QTLs for height were mapped in the linkage group（LG） B1,LG D1a,LG G by software WinQTLCartographer Ver.2.5.Furthermore,not only 78 QTLs of height that have been mapped in many different populations and environments were collected but also QTLs mapped by WinQTLCartographer Ver.2.5 were projected and integrated the reference map with the software BioMercator2.1.In total,12 consensus QTLs and their corresponding markers were obtained respectively.The minimum C.I.was shrunk to 0.24 cM.These results would lay the foundation for mapping QTL precisely in soybean.
