摘要: The complete diallel cross design was employed to estimate the genetic parameters of the growth of Japanese flounder (Paralichthys olivaceus). A total of 60 full-sib families were cultivated and two growth-related traits, body weight (BW) and body length (BL), were examined at average 2, 3 and 8 months of age respectively, with 1 800 individuals measured in each age group (30 per family). Based on the additive-dominance-maternal-effect genetic analysis model, the restricted maximum likelihood approach was used to estimate various (co)variance components. The results showed that narrow-sense heritability estimates of BW and BL were respectively: 0.29 +/- 0.01 and 0.22 +/- 0.02 at 2 months of age, 0.32 +/- 0.02 and 0.30 +/- 0.04 at 3 months of age, 0.48 +/- 0.04 and 0.40 +/- 0.05 at 8 months of age; broad-sense heritability estimates were respectively: 0.44 +/- 0.02 and 0.54 +/- 0.04 at 2 months of age, 0.35 +/- 0.01 and 0.36 +/- 0.03 at 3 months of age, 0.49 +/- 0.03 and 0.45 +/- 0.04. All heritabilities were statistically significant (P < 0.05). Additive genetic correlations between BW and BL at 2, 3 and 8 months of age were consistently positive and highly significant (P < 0.01): 0.93 +/- 0.02, 0.95 +/- 0.03 and 0.92 +/- 0.03 respectively. Maternal effect was significant (P < 0.05) only at 2 months of age, and was not detected at 3 and 8 months of age. According to the heritability estimates, the mass selection strategy should be efficient for the breeding of Japanese flounder.
