If the poultry industry hopes to continue to flourish, the identification ofpotential quantitative trait loci (QTL) for production-related traits must bepursued This remains true despite the sequencing of the chicken genome. In viewof this need, a scan of the chicken genome using 72 microsatellite markers wascarried out on a meat-type x egg-type resource population measured forproduction and egg quality traits. Using a Bayesian analysis, potential QTL fora number of traits were identified on several chromosomes. Evidence of eight QTLregions associated with a total of eight traits (specific gravity, albuminheight, Haugh score, shell shape, total number of eggs, final body weight, gain,and feed efficiency) was found. Two of these regions, one spanning the area of263/287 cM on GAA01 and the other spanning the area of 23/28 cM on GAA02, wereassociated with multiple QTL.
