n individuals’ refers to the number of individuals assessed for each trait. 'n families’ refers to the number of families assessed for each trait. 'Age’ refers to the age of the plants at the time that a trait was assessed in number of months after the trial was planted. 'Transformation’ refers to the power transformation used to standardise the variance of each trait (x). 'Mean’ refers to the backtransformed mean of all assessed individuals for each trait.
