Plant height is one of very complicated quantitative traits of soybean yield and the phenotype data is variable to environment. Since molecular marker technology appeared, many studies about soybean height QTL have been reported. 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. The results showed that 15 QTLs for plant height were mapped in the linkage group (LG) B1, LG D1a, LG G by software Windows QTL Cartographer Ver. 2.5. Furthermore, another 78 QTLs of plant height mapped in different populations and environments were collected, combined with the QTLs above, projected and integrated the reference map with the software BioMercator2.1. Finally, a total of 12 consensus QTLs and their corresponding markers were obtained respectively. The minimum CI was shrunk to 0.24 cM. These results would lay the foundation for mapping plant height QTL genes precisely in soybean in future.
