The invention relates to a single nucleotide polymorphism (SNP) marker related to a Chinese horse short stature trait. The SNP molecular marker is located at the 501position of a sequence shown in SEQ ID NO.1, polymorphism is G/A, and the SNP marker corresponds to base pair 18,205,998 on chromosome 8 in a horse. The SNP marker related to the Chinese horse short stature trait and use thereof provided by the present invention have the following advantages that: (1) the molecular marker is not restricted by the age, sex and the like of Chinese horses, is used in early breeding of the Chinese horses, performs accurate screening immediately at birth, and significantly promotes the breeding process of dominant pony varieties of the Chinese horse; (2) a method for detecting SNP of a Chinese horse TBX3 gene is accurate, reliable, and easy to operate. 110.-. (canceled)12. A kit or reagent comprising the specific primer combination according to .13. A method for using the specific primer combination according to or the kit or reagent according to in identifying pony varieties of Chinese horse claim 11 , molecular marker-assisted breeding of Chinese horses claim 11 , or improving germplasm resources of Chinese horses.14. The method according to claim 13 , wherein a method for identifying pony varieties of Chinese horse comprises the following steps:1) extracting genomic DNA from a test horse;2) using the genomic DNA of the test horse as a template to conduct polymerase chain reaction (PCR) amplification with specific primers, to obtain a fragment of an amplified product; and3) determining what type of a base is located at 501 bp in the fragment of the amplified product: if the base is A, then the test horse is determined to have a short stature trait; if the base is G, the test horse is determined to have a tall stature trait; namely, in the detection, an idiotype with fluorescence of primer 1 labeled groups is AA, and an idiotype with fluorescence of primer 2 labeled groups ...
