Table 3 Test of univariate equality of group means to estimate the efficiency of different characters in separating the groups. Low values for Wilks’ lambda indicate that the within-group variability is small compared to the total variability, thus most of the total variability is attributable to differences between the means of the populations and families, respectively. All values are highly significant (P < 0.0001). Values of Wilks’ lambda corresponding to the most efficient characters are printed in bold
