Abstract:
A ＲILs population derived from a cross between Dongnong 46 and L-100 was used in the experiment. The differentgeneration populations were evaluated in three locations( Harbin，Hulan and Acheng) ，in 2013 and 2014 using single-enviromentQTL analysis and multi-enviroment joint analysis. The results showed that，thirteen QTLs were detected associated withseed shape in single-enviroment QTL analysis，located in 5，9，12，15，and 18 linkage group. Two QTLs were associatedwith seed length，explained 21. 61% － 26. 81% of the phenotypic variation. Five QTLs were associated with seed width，explained7. 28% － 18. 38% of the phenotypic variation. Six QTLs were associated with seed thick，explained 10. 19% －18. 44% of the phenotypic variation. The QTLs located in the marker interval of Sat_122 － Satt052 associated both seed lengthand seed thick. The QTLs located in the marker interval of Sat_119 － Satt588，Satt192 － Satt568 and Sat_401 － Satt192 associatedboth seed width and seed thick，showed pleiotropy. Fifteen QTLs were detected associated with seed shape in multi-enviromentjoint analysis. Nine QTLs were detected in both methods，showed genetic stability.
