a – ID of provenances is identical to Fig. 1 and the study of Bednorz (2006);
b – classification on the basis of Kabała et al. (2019).

Figure 2.
The original layout of the JAM (A) and SYC (B) common garden trials. Different colours denote provenances, and the numbers (labels) on the layout represent OP families within those provenances. The labels of the OP families correspond to those in Table 2; for example, the red 10 stands for OP family 15/10. The experiments are divided into sub-blocks: at the JAM site, sub-blocks 1, 2, and 3 are left, middle, and right, respectively; at the SYC site, sub-blocks 1, 2, 3, and 4 are top left, bottom left, top right, and bottom right, respectively. The north direction is the same for both sites
