Test of local adaptation after controlling for site‐of‐origin and planting site effect. Generalized linear models testing for Sympatric versus Allopatric (SA), the difference between the average fitness in sympatric combinations and the average fitness in allopatric combinations. Differences in SA are indicated by the “Home versus Away (HA)” term, whereas the other terms test for site‐of‐origin and planting site effects. Data were considered as a binomial (survival) or continuous (other traits). For survival, significance is based on the likelihood ratio (G), while for the continuous variables, it is based on an F test
