摘要: Genetic parameters for resistance to Vibrio anguillarum in Scophthalmus maximus were estimated using three different statistical models. Data were recorded from an experimental infection performed on 2,400 individuals from 30 full-sib groups. Cross-sectional linear model and cross-sectional threshold probit model were used to analyse the test-period survival; the cross-sectional threshold logit models were used to analyse the test-day survival. The heritability values estimated by cross-sectional linear model (CSL), cross-sectional threshold (probit) model (THRp) and cross-sectional threshold (logit) model (THRl) were 0.202 +/- 0.101, 0.296 +/- 0.168 and 0.110 +/- 0.023, respectively. The correlation coefficients between the full-sib families' estimated breeding values (EBVs) based on these three models were over 0.993. An almost identical ranking of families was generated using any of these models. Accuracy of selection using CSL, THRp and THRl models was 0.783, 0.789 and 0.801, respectively. Accuracy of selection based on the THRl model was higher than that based on CSL and THRp models.
