主　　题：Oryza glumaepatula GL9 Grain size Grain chalkiness Single-segment substitution line 

摘      要：Grain size is a key factor influencing grain yield and appearance quality in *** identified twelve quantitative trait loci(QTL)for grain length(GL),nine for grain width(GW),and nine for 1000-kernel weight(TKW)using GLU-SSSLs,which are single-segment substitution lines with Oryza glumaepatula as donor parent and Huajingxian 74(HJX74)as recipient *** the QTL,qGL1-2,qGL1-4,qGL9-2,qGW2-2,qGW9-1 and qTKW9-2 contributed to high grain ***9 was identified as a candidate gene for qGL9-2 by map-based cloning and sequencing,and is a novel allele of *** kernel of NIL-gl9was slenderer and longer than that of HJX74,and the TKW and grain yield per plant of NIL-gl9 were higher than those of *** proportion of grain chalkiness of NIL-gl9 was much lower than that of ***,gl9 increased grain yield and appearance quality *** pyramid lines,NIL-gs3/gl9,NIL-GW7/gl9 and NIL-gw8/gl9,were developed and the kernel of each was longer than that of the corresponding recipient parent *** gl9 allele may be beneficial for breeding rice varieties with high grain yield and good appearance quality.
