| Outline of Final Research Achievements |
We first performed detection of polymorphisms in positional functional candidates for the genes responsible for growth traits in Landrace pig breed with direct-sequencing and establishment of genotyping method. Based on association study with Landrace pig population, the D-Loop/846 SNP determining specifically mitochondrial D-Loop haplotype 4 showed a significant effect on the maternal lineage effect for the age at 100 kg. Further, the COQ3/-1623 indel polymorphism in the nuclear COQ3 gene was associated with the predicted breeding value for the age at 100 kg. In conclusion, we suggested that the two polymorphisms are useful for effective marker-assisted selection to increase of growth rate in Landrace pig breed.
