Values are means (standard deviations); lower case letters indicate significant differences among means based on Tukey's HSD, and +/− indicate when variances are significantly higher or lower than expected, based on Levene's tests. Selection differentials were calculated when there was a difference between the original and field-collected seeds. When field sites did not differ significantly from one another, differentials were based on pooled means/standard deviations and were calculated separately for each field site when they differed.
