Abstract

Abstract: Cross was made using high protein content variety Jidou 12 as female parent and high oil content variety Jihuang 13 as male parent,and get F9 RIL population with 148 single plants.The linkage map of this population was made using F9 family.The quantitative characters such as protein and oil content as well as yield related charcaters such as plant hight,first pod hight,branch number,nod number,efective pod,sterile pod,seed weight per plant,seeds per plant were recorded and mapped.15 QTLs for 10 characters were detected.The QTLs of protein and oil content were located on A2 linkage group,and the contribution rate is 10% and 16% respectively.The result also showed that most QTLs of the characters corelatited to yield were located on C2 linkage group.

Key words: Soybean, Gene mapping, Protein, Oil, Quatitive trait loci
