摘　　要：基于Charleston×东农594重组自交系群体,采用完备区间作图和混合线性模型对2006-2010年连续5年的百粒重QTL进行定位,并进行基因×环境互作及上位性分析。结果定位了16个与大豆百粒重性状相关的QTL,其中有5个QTL分别与环境发生互作,互作贡献率在0.11%～0.52%之间;定位了8对上位互作位点,贡献率在1.15%～2.59%之间。The epistatic effects and genotype × environment interaction played an important role of plant genetics,evolution and heterosis,which had been confirmed by a large number of research.100-seed weight（100-SW） was an important parameter in measuring soybean [Glycine max（L）.Merr.] yield and controlled by multiple genes.Soybean 100 quantitative trait loci（QTLs） were analyzed from 2006 to 2010 via recombination inbred lines（RIL） population derived from a cross between Charleston and Dongnong 594.The objective of this study was to investigate epistatic effects and QE interaction effects of QTLs for 100-SW by Inclusive Composite Interval Mapping（ICIM） and the mixed linear model.Finally,16 QTLs were mapped.Among them,five 100-SW QTLs with QE interaction contributed 0.11%~0.52%.And 8 QTLs pairs with epistatic effects were detected,accounting for 1.15%~2.59% of the general phenotypic variation.
