High-throughput sequencing technologies bring us the genomics age, consequently facilitates genome-wide association studies (GWAS) of complex traits in crops. But GWAS has not yet been successful in detecting the genetic basis of phenotypic variations in rice due to limited mapping resolution. Recently, chinese scientists have cloned a QTL for rice grain length and weight using GWAS combining with functional investigations and propelled the molecular dissection of rice QTL from genetics to genomics. Their study provided us not only a model for investigating rice complex traits and evolutionary changes using “omics” resources but also a valuable gene for rice breeding.
