Scylla paramamosain carapace length related SNP (Single Nucleotide Polymorphism) molecular marker, detection primer pair, kit and application
Through genome-wide correlation analysis, SNP sites related to dorsal carapace length on the chromosome 4 of the pseudo-crawan crawan were determined, and SNP molecular markers and detection tools were developed, which solved the problem of difficulty in identifying dorsal carapace length-related SNP markers in the existing technology, and achieved efficient evaluation and breeding of the dorsal carapace length traits of the blue crab, significantly accelerating the genetic improvement process.

AI Technical Summary
The prior art has not yet successfully identified SNP markers directly related to the long trait of the dorsal carapace of the simile blue crab through GWAS analysis of whole genome resequencing technology, and it is difficult to evaluate and breed individual phenotypes in the early stages.
Through genome-wide association analysis, it was determined that the G>T mutation at locus 31207983 on chromosome 4 of the pseudo-caryng Crab was significantly correlated with the dorsal carapace length trait. SNP molecular markers related to dorsal carapace length were developed, and primer pairs and kits were designed to detect the SNP marker.
The efficient evaluation and breeding of the long traits of the dorsal carapace of the blue crab were achieved, and the long traits of the dorsal carapace were gradually improved through genome selection, which significantly accelerated the genetic improvement process of the blue crab and improved the economic benefits of the breeding industry.
