Figure 1. Electrophoretic results of some materials with five pairs of primers (E-ACA-M-CTT, E-AGC-M-CTG, E-ACT-M-CTC, E-ACC-M-CAT and E-AAG-M-CTA).
Figure 2. Geographic locations of S. tonkinensis. The colours of circle dots represent the clade to which dots belong. Orange: clade I, Blue: clade II, Red: clade III. Source: Constructed by software DIVA-GIS.
Figure 3. Information on band pattern. Note: The data were processed by GenAlEx 6.5.

Figure 4. Estimated number of subpopulations (K). Note: The studied panel from STRUCTURE 2.3.4 analysis.
Figure 5. Genetic structure and dendrogram. Note: Genetic structure was constructed using Bayesian method by STRUCTURE 2.3.4 and UPGMA dendrogram was drawn based on Nei’s genetic distance by NTSYS-pc v2.10.
Figure 6. Principal coordinate analysis (PCoA) based on AFLP data. Note: PCoA with Nei’s genetic distance and data processed by GenAlEx 6.5.
