'Age’ refers to the time that each trait was assessed after the trial was planted. 'Rep.iblock’ refers to the random effect of replicate.incomplete-block. 'Additive’ refers to additive genetic variance. 'Error’ refers to the random effect of residuals. 'V_P’ refers to the phenotypic variance. 'CV_A’ refers to the coefficient of additive genetic variance. 't’ refers to the t-value for Additive and 'Pr > t’ refers to its significance. 'Rep’ and 'Sex’ refers to the fixed effects of replicate and plant sex on the trait, respectively; 'P > F’ refers to their significance in each case. 'h²’ refers to the narrow-sense heritability and 'SE’ refers to standard error of h².
