AI Technical Summary

Technical Problem

There are few existing studies on molecular markers for meat yield traits in red swamp crayfish, which cannot meet the needs of high-quality and high-efficiency breeding.

Method used

Ten SNP molecular markers, SNP1 to SNP10, were screened through genome-wide association analysis to detect the meat yield trait of Procambarus clarkii. Genotyping was performed using PCR amplification technology to select individuals with high meat yield for breeding.

Benefits of technology

This significantly improves the breeding efficiency and accuracy of Procambarus clarkii, enabling the breeding of high-yield and high-quality new varieties to meet the needs of high-quality and high-efficiency breeding.

Abstract

The application discloses a SNP molecular marker related to a Procambarus clarkii meat yield character and application thereof, and relates to the following steps: genotyping P. clarkii through whole genome association analysis, performing whole genome association analysis on the meat yield of P. clarkii, and screening out SNP markers significantly related to the meat yield character, including one or more of SNPs 1-SNPs 10. In the application, the P. clarkii with high growth speed and high meat yield can be effectively predicted and selected by detecting the above-mentioned SNP markers, the selection efficiency and accuracy of the P. clarkii are significantly improved, and a new P. clarkii variety with high yield and high quality is selected, so that the application has a wide application prospect in the molecular breeding of the meat yield character of the P. clarkii.
