A Hinf Ⅰ locus of the porcine subunit C of succinate dehydrogenase complex (SDHC) gene and a Msp Ⅰ locus of theporcine rod cGMP-phosphodiesterase γ-subunit (PDE6G) gene had been reported before, but the association...A Hinf Ⅰ locus of the porcine subunit C of succinate dehydrogenase complex (SDHC) gene and a Msp Ⅰ locus of theporcine rod cGMP-phosphodiesterase γ-subunit (PDE6G) gene had been reported before, but the association analysisbetween the different genotypes and the traits had not been done. 300 Large White × Meishan F2 pigs were used asexperimental materials to performe the PCR-RFLP analysis and association analysis for the two loci, results revealed thatthe polymorphism of the porcine subunit C of succinate dehydrogenase complex (SDHC) gene was significantly associatedwith the traits which included the carcass length, the estimated lean meat percentage, the estimated backfat thickness atlast rib, the estimated backfat thickness at last 3-4th rib, the fat meat weight, the fat meat percentage, the lean meat weight,the lean meat percentage, the ratio of lean meat to fat meat, the leaf fat weight, the backfat thickness at shoulder, thebackfat thickness at thorax-Waist, the backfat thickness at 6-7th thorax and the average daily gain. Seven other traits, themeat color value (Biceps femoris, BF), the meat marbling (Biceps femoris, BF), the water moisture (Longissimus dorsi, LD),the bone weight, the bone percentage, the loin eye width and the loin eye area, were found to be significantly correlatedwith the polymorphism of the porcine rod cGMP-phosphodiesterase γ-subunit (PDE6G) gene. Based on these results, itis necessary to apply the two genes as candidate genes to marker assistant selection (MAS) in pig breeding.展开更多
