Abstract / Description of output

A Brazilian F2 resource population, derived from a broiler layer cross, was used to map QTL for performance, carcass traits and organs weight on chicken chromosomes 6 to 8, 11 and 13. A total of 356 F2 chickens from four full-sib families were genotyped with 26 microsatellite markers. Regression methods were applied to a line cross model in the QTL interval mapping analyses. A suggestive QTL affecting five growth-related traits and feed intake was identified on chromosome 7. QTLs associated with feet weight were detected on chromosomes 6 and 11, with gizzard weight on chromosomes 8 and 11, and with heart weight on chromosome 13.
