苏姜猪A-FABP基因遗传多态性及其与肉质性状的关联分析
Genetic Polymorphism of A-FABP Gene and Correlation Analysis with Meat Quality Traits in Sujiang Swine
摘要
Abstract
Aesearch by PCR-RFLP technical analyzed Sujiang swine,Jingquhai swine and landrace groups' A-FABP genetic polymorphisms,and analyzed the correlation between loci polymorphism and meat quality traits.Results showed that the three swine-breeds' A-FABP gene intron 1 have BsmI enzyme polymorphisms,three genotypes were detected (AA,AB,and BB).The Chi-square test results showed that three swine-breeds' A-FABP genotype distribution in Hardy-Weinberg equilibrium (P＞0.05).Polymorphism information content (PIC),which were moderately polymorphic in three varieties of swines.According to the association analysis of different genotypes of marbling and intramuscular fat content(IMF),significant difference was found in marbling,genotype AA,AB was significantly higher than BB (P＜0.05),intramuscular fat content genotype AA was significantly higher than AB,BB (P＜0.05).Conclusion showed that Sujiang swine,Jiangquhai swine and landrace groups'A-FABP gene intron 1 polymorphism had significant effects on meat quality traits.关键词
