*Significance of population and population-by-environment interaction effects determined by two-way ANOVA, with population analyzed as a random effect and environment as a fixed effect.

^†Values that remain significant (P < 0.05) following sequential Bonferroni correction for the four tests performed within each resource set are shown in bold.
