The recombinant inbred lines(RIL),including 158 lines,from the cross BOGAO×NG94-156,were used as experimental materials in this study.Based on the linkage map construc- ted mainly with single sequence repeat(SSR)markers using this RIL population,the software WinQTL Cart V2.5 and the composite interval mapping were employed to identify quantitative traits loci(QTL)associated with shelling percentage of fresh pod in 2005 and 2006 years.It was found that the results of mapping QTL for shelling percentage were similar for these two years.Two QTLs mapped on linkage group E and N could be detected in two years,and they could be explained 7.59%-10.04% of the total variation of the shelling percentage,respective- ly.In addition,the software QTL Mapper 1.6 was applied to detect QTLs and estimate additive environment interaction effects of QTLs.The result indicated that the results of mapping QTL for shelling percentage were similar for these two methods.There were one QTL with additive envi- ronment interaction effect.The QTL for shelling percentage of fresh pod mapped firstly in this study,which will serve as a solid platform for the molecular marker assisted selection.
