In the present invention, a composition comprising a SNP marker set composition for genotyping analysis of a pine tree population, a composition comprising an agent capable of detecting or amplifying the SNP marker set, a microarray comprising the SNP marker set, and a genotype of a pine tree population comprising the composition A kit for analysis, and a method for genotyping a pine population are disclosed. Using the novel SNP marker set composition, probe, and microarray or kit including the same according to the present invention, genotyping analysis of a large number of pine populations can be performed easily and accurately. In addition, the results of genotyping of pine trees can be used for analysis of genetic variation of pine trees, evaluation of genetic resources, individual identification, genome and molecular breeding studies.
