Table 3.
Representatives of putative P. sylvestris × P. mugo hybrids grouped into two groups according to the WSS value. The WSS weights sum up to 1. Pure P. sylvestris or P. mugo subsp. uncinata WSS indexes add up to 1 and 0, respectively (based on our observation; not shown). Number at the tree ID indicates the tree age (at least, based on phenotype). Trait abbreviations are explained in Table 1.
