Structure analysis of the genetic relationship between 12 populations. K is the possible numbers of parental population clusters. One color represents one parental population cluster. Each individual is represented by a vertical column partitioned into different color segments. Most suitable K was observed at K = 5, where the proportion of each ancestral component in a single individual is represented by a vertical bar divided into 5 colors
