| Abstract: | The aim of this study is to screen single nucleotide polymorphisms (SNPs) of the farnesoic acid O‐methyltransferase gene in shrimp, Penaeus chinensis (PcFAMeT), and analyze the potential association between PcFAMeT gene polymorphisms and growth traits in a cultured population. Four SNPs (A163G, G392T, A708G, and T752C) were tested for association with six growth traits in 240 individuals using the polymerase chain reaction‐restriction fragment length polymorphism (PCR‐RFLP) method. The association analysis of SNPs of PcFAMeT gene with the six growth traits was carried out using general linear model estimation. Results indicated that SNP2 (G392T) of the PcFAMeT gene was significantly associated with body weight (P < 0.05) and carapace width (P < 0.05). The individuals of genotype GG grew faster than those of genotype GT and TT. The results would provide potential application in future shrimp breeding programs and may be used to improve the efficiency in shrimp, P. chinensis, breeding programs. |
