Última Use of Analytic Factor Structure to Increase Heritability of Clonal Progeny Tests of Pinus taeda L. Chilean J. Agric. Res. Zapata-Valenzuela,Jaime. Advanced variance-covariance structures are commonly used in genetic evaluation of crops to account for micro-site variability and achieve higher accuracy of predictions to increase selection efficiency. Various genetic variance-covariance structures were explored to predict best linear unbiased genetic merits of 453 loblolly pine (Pinus taeda L.) cloned progeny tested at 16 different locations in the southern U.S. Statistical models were compared using model fit statistics, variance components and genetic parameters. Among the models explored, spatial autoregressive error correlation with independent residual term for the R side with a factor analytic structure for the G side of the mixed model was superior. The model produced one of the smallest fit... Tipo: Journal article Palavras-chave: Linear mixed model; Quantitative forest genetics; Genetic variance.
