A three-generation resource family was developed using two Berkshire grand sires and nine Yorkshire grand dams to detect QTL for meat quality traits in pigs. A total of 525 F2 progeny from 65 F1 matings were produced. All F2 animals were phenotyped for 40 growth, carcass, meat quality and sensory traits, and genotyped for 125 microsatellite markers covering the genome. Significance thresholds were determined by permutation tests.
Additional marker analyses and examination of positional candidate genes are underway.
