Molecular genetic analysis of an Atlantic salmon (Salmo salar) broodstock: Pedigree analysis and QTL detection for body weight
A multiplex genotyping system was applied to Atlantic salmon (' Salmo salar') being reared by the Atlantic Salmon Broodstock Development Program in Chamcook, New Brunswick. Nine microsatellite loci were used to determine the parents of 98% of 305 progeny from the 1998 year-class reared in...
