- Molecular genetic markers were genotyped used to detect chromosomal regions which contain
economically important traits such as growth, carcass, and meat quality traits in pigs. Three
generation resource population was constructed from a cross between the Korean native boars and
Landrace sows. A total of 193 F2 animals from intercross of F1 were produced. Phenotypic data on
13 traits, birth weight, body weight at 3, 5, 12, 30 weeks of age, live empty weight, backfat
thickness, muscle pH, meat color, drip loss, cooking loss, and shear force were collected for F2
animals. Animals including grandparents (F0), parents (F1), offspring (F2) were genotyped for
194 microsatellite markers covering from chromosome 1 to 18. Least squares regression interval
mapping was used for quantitative trait loci (QTL) identification. Significance thresholds were
determined by permutation test. Fifteen QTL were detected at 5% chromosome-wide significance
level for growth traits on chromosome 1, 5, 7, 13, 14, and 16, and for meat quality traits on
chromosome 5, 6, 7, 10, 11, 15, and 18. Two QTLs out of these were significant at the 1%
Chromosome-wide level for meat color on chromosome 7, and for muscle pH on chromosome 11.
