Table 1.

Quantitative trait differentiation of tree phenotypic traits in three common garden sites. Estimates and 95% credible intervals of Q _ST from both the three local populations with genotypic replication, and using the mean H ² to estimate the genetic variance for all nine populations are presented. Broad sense heritability (H ²) pooled across the entire collection and broad sense heritability (H ²) pooled from the hierarchical analysis within populations are both presented
