摘      要：Grain size is one of the critical agronomic traits governing grain yield and quality in ***,the underlying genetic mechanisms that control grain size in rice are poorly *** used an introgression line derived from Zhonghui 8015 and Oryza rufipogon *** introgression line was evaluated under two different environmental conditions to dissect the quantitative trait loci controlling grain ***-wide association study(GWAS)was performed using 28193 SNPs through a general linear model,and 56 significant SNPs on different loci associated with the 4 grain size traits were *** genes including GS3 and q GL3 showed substantial effects on grain length and *** new stable loci were identified with pleiotropic effects on grain ***,gene expression analyses,combined gene-based associations,and functional annotations permitted the shortlisting of important dominant genes including GS3 and q GL3.
