Histogram of the STRUCTURE analysis for the model with K=3 (showing the highest ΔK) based on the nSSR data of 381 individuals (12 populations) of L. chinense from the TIL region and the Zhoushan Archipelago. Each colour corresponds to a suggested cluster, and a vertical bar represents a single individual. The x axis corresponds to population codes. The y axis presents the estimated membership coefficient (Q) for each individual in the three clusters.
