Abstract

The purpose of this study was to identify genomic regions of quantitative trait loci (QTL), affecting
carcass traits on chromosome 1 in an F2 population of Japanese quail. For this purpose, a three-generation
resource population was developed by using two distinct Japanese quail strains, wild (meat type) and
white (layer type). Eight pairs of white and wild birds were crossed reciprocally and 34 F1 birds were
produced. The F1 birds were intercrossed to generate 422 F2 offspring. Phenotypic data including weight
of carcass parts were collected on F2 birds. All of the animals from three generations (472 birds) were
genotyped for eight microsatellite markers on chromosome 1. QTL analysis was performed with least
squares interval mapping method fitting three various statistical models. Significant QTL were identified
for breast weight, carcass weight, head weight and percentage of breast. There was also evidence for
imprinted QTL affecting breast weight, a carcass part of high economic value, on chromosome 1. The
proportion of the F2 phenotypic variation explained by the significant additive, dominance and imprinted
QTL effects ranged from 1.8 to 2.3, 1.2 to 3.3 and 0.5 to 2.2 percent, respectively.
