Abstract:

In order to investigate the relationship between the polymorphism of type 1 vasoactive intestinal peptide receptor (VIPR-1) gene and carcass traits of meat quail, the polymorphism of VIPR-1 gene was detected by PCR-RFLP method in two populations, including French giant meat quail and Savimaito meat quail, and the correlation between the polymorphism of VIPR-1 gene and carcass traits of meat quail was analyzed. The results showed that GG, GT and TT genotypes were detected at the BsrDⅠ locus of exon 4-5 of VIPR-1 gene in French giant meat quail and Savimaito meat quail, the GG, GT and TT genotype frequencies of French giant meat quail and Savimaito meat quail were 0.408, 0.490, 0.102; 0.222, 0.444, 0.334, respectively. AA, AG and GG genotypes were detected at the HpyCH4Ⅳ locus of exon 6-7 of VIPR-1 gene in French giant meat quail and Savimaito meat quail, the AA, AG and GG genotype frequencies of French giant meat quail and Savimaito meat quail were 0.020, 0.020, 0.960; 0.056,0.111,0.833, respectively. The results of association analysis showed that the BsrDⅠ locus in exon 4-5 of VIPR-1 gene was significantly associated with the liver weight of French giant meat quail (P<0.05). The HpyCH4Ⅳ locus in exon 6-7 of VIPR-1 gene was significantly associated with body weight, slaughter weight and liver weight of French giant meat quail (P<0.05), and with the body weight, slaughter weight, eviscerated weight, heart weight, chest muscle weight, leg muscle weight, liver rate and chest muscle rate of Savimaito meat quail (P<0.05). The VIPR-1 gene can be used as a candidate gene for marker-assisted selection of carcass traits in meat quail.
