The invention relates to a four-primer molecular marking method for identifying different genotypes of a rice grain length gene GS3, belonging to the technical field of agricultural bioengineering. Four marking primers are designed and synthesized according to differences of a long and large-grain variety TD70 and a short and small-grain variety Kasalath in the nucleotide base sequence of the grain length gene GS3, and are added into the same PCR system for amplifying different rice DNA so as to distinguish different genotypes of homozygotes and heterozygotes of the GS3. The method disclosed by the invention not only can be used for rapidly and accurately identifying the different genotypes of the grain length gene GS3 in a rice genetic resource or a breeding population but also can be used for improving the selection efficiency on a long-grain genotype GS3-TGS3-T and speeding up the breeding progress of a new long-grain, high-quality and high-yield rice variety.
