ABSTRACT
Quail is extensively cultured in China for characteristic of quick growth, small fodder consumption, early sexual maturity, big egg output and short production period. To recognize molecular markers of egg quality of quail, SNP in control regions of cytogenin gene (MyoG) 5’ in China yellow quail, Beijing white quail, Korean quail detected by PCR-SSCP method in this study. Moreover, correlations of control regions of MyoG 5’ with egg quality of quail were analyzed. Results demonstrated that: In egg quail group, six genotypes were detected in Locus A in the control region of MyoG 5’, including AA, BB, CC, AB, AC and BC. The C allele frequency at Locus A in China yellow quail, Beijing white quail and Korean quail was the highest (0.461, 0.528 and 0.579). A total of 9 genotypes were detected in locus B in egg quail group, which were AA, BB, CC, DD, EE, AB, AC, AD and AE. The C allele frequency at Locus B in China yellow quail, Beijing white quail and Korean quail was the highest (0.612, 0.623 and 0.633). The egg shape index and yolk index of egg quail are significantly correlated with locus B (P<0.05). However, locus A has no significant impacts on egg quality of egg quail (P>0.05).
