This invention provides a gene related to loquat flowering. SVP1 This invention relates to the field of molecular biology, specifically to a tightly linked SNP marker and its applications. The nucleotide sequence of this SNP marker is shown in SEQ ID NO.1. A genotype of C at the locus corresponds to a spring-flowering phenotype in loquat, while a genotype of G corresponds to an autumn-flowering phenotype. The invention also provides specific primers (SEQ ID NO.2 and SEQ ID NO.3) for detecting this SNP marker, a kit containing these primers, and a screening method for detecting loquat flowering time using this marker. By extracting loquat DNA and performing PCR amplification and sequencing analysis, the flowering period of loquat can be quickly and accurately determined.
