Population structure of the soybean mini core collection. The LnP(D) and Delta K values when k from 1 to 15 shows in Fig (a). Fig (b) shows the q value of soybean accessions belonged to two subgroups. The subgroup 1 shows in green color and subgroup 2 shows in red color. The vertical coordinate of each subgroup indicates the q value for each individual, and the digits on the horizontal coordinate represent the origin region of soybean
