The development of cytoplasmic male sterile(CMS)line has facilitated the utilization of soybean heterosis.It was confirmed that the fertility restoration of the RN type soybean CMS line was controlled by a single dominant nuclear gene.Two SSR makers,Satt414 and Satt596,which were genetically linked to the nuclear restorer gene,were selected by screening of SSR markers with F2 segregation population from the cross between sterile line YA and restorer line 167.The genetic distance between the markers and the restorer gene were 16.4 and 14.6 cM,respectively.A segregating population developed from a cross between more diversified parents was used for screening the closer SSR markers.SSR marker Satt547 with genetic distance of 7.56 cM to the restorer gene was identified.The nuclear restorer gene was located in J linkage group according to Cregan's soybean genetic map.
