This invention discloses a SNP molecular marker associated with the growth traits of *Bellamya pear-shaped* and its application, belonging to the field of marker-assisted breeding technology. The SNP molecular marker is located at loci 131,293,660 on chromosome 4 of *Bellamya pear-shaped* (T>C variant), where the T allele (genotypes T / T and T / C) is significantly positively correlated with growth rate and body weight. This invention integrates genome-wide association analysis (GWAS) with an XGBoost machine learning model to screen key loci and designs specific primer pairs to achieve accurate genotyping. Population validation shows that individuals carrying the T allele have significantly higher growth rates and average body weights than individuals with the C / C genotype. This marker can be used for early prediction of growth performance in *Bellamya pear-shaped*, selection of high-yielding varieties, and construction of genetic maps, overcoming the bottlenecks of long breeding cycles and low efficiency in traditional breeding methods.

This invention relates to the field of genetic engineering technology, and in particular to a CgFAD gene that regulates fruit base length and its applications. The amino acid sequence of the protein encoded by the CgFAD gene described in this invention is shown in SEQ ID NO.1. This invention, through analysis of transcriptome data (RNA-seq) of the fruit base development process of Guanxi Honey Pomelo (long-base pomelo germplasm) and Pingshan Pomelo (short-base pomelo germplasm), discovered a CgFAD gene that can regulate fruit base length. This CgFAD gene negatively regulates the fruit base length of pomelo fruits; that is, the higher the expression level, the shorter the fruit base length. Experiments using overexpression of Huangyang pear-shaped tomatoes confirmed that the CgFAD gene can negatively regulate fruit base length, providing a new gene resource for fruit shape improvement.
