Multi-environment trial of trees, height / survival of 37 species at 6 sites in Thailand
A data frame with 222 observations on the following 4 variables.
Environment factor, 6 levels
Genetic factor, 37 levels
Planted in 1985 at six sites in Thailand. RCB with 3 reps. The data
here is the mean of the three reps. Plots were 5 meters square with
spacing 2m x 2m. Measurements collected at 24 months. The
column in the data is actually seedlot, as some tree species
have multiple seed lots. The trees are mostly acacia and eucalyptus.
