Agronomic and quality traits such as grain shape,1000grain weight, and physicochemical properties are quantitative traits that are controlled by mutli-genes and affected by genotype by environment interaction. Dissection of the genetic basis of these complex traits is difficult. Deep dissection and utilization of the important genetic variations is very important for rice breeding. With the technical development of mining the single nucleotide polymorphisms (SNP) in target genome, genome-wide association st...
