Sixty-six SSR markers, 38 CAPS markers, and RAD-seq data from
288 positions were used for screening polymorphic loci among 22 inbred lines (Table S2). The software Populations version 1.2.31 (http://
bioinformatics.org/~tryphon/populations/) was used to calculate the genetic distance among inbred lines and to construct a neighbor-joining
phylogenetic tree with 1000 bootstraps (Nei et al., 1983). The tree
was depicted using TreeView version 1.6.6 (http://tree.bio.ed.ac.UK/
software/figtree/).
