摘要： Genetic parameters and response to selection were estimated for harvest body weight in turbot. The data consisted of 10 952 individuals of 508 full-sib families from three generations (G0, G1, and G2). The heritability estimates for G0, G1, and G2 were 0.11 +/- 0.08, 0.18 +/- 0.09, and 0.17 +/- 0.07, respectively. Over three generations, the heritability estimate was 0.19 +/- 0.04. Maternal and common environmental effects were 0.10 +/- 0.04, 0.14 +/- 0.04, and 0.13 +/- 0.03 within each generation and 0.12 +/- 0.01 across generations. The selection differential in growth was 18.24 g in G0 and 21.19 g in G1 corresponding to an average of 19.72 g per generation. The genetic gains were also calculated, they were 22.06 g in G1 and 11.93 g in G2, corresponding to 6.36% and 3.52% body weight. The total genetic gain after two generations was 10.10% body weight, which indicated that the selective breeding program for the body weight trait in turbot was successful.
