| Research Abstract |
This study aimed to specify genetic locus (QTL)that controlled quantitative traits such as meat production and meat quality traits, and to develop the method of rapidly increasing the improvement efficiency in pigs. The leptin receptor gene (LEPR)was specified on the sixth chromosome for a gene concerning the fat accumulation, and SCE gene was specified on the 14th chromosome for a gene concerning the fatty acid (C18:0 and C18:1), as a result of QTL analysis and a fine-mapping for Duroc purebred population. Simulation analysis on the efficiency of improvement for the oleic acid (C18:1)resulted that the selection system that used SNP information was highest in the efficiency of improvement.
