Fig.1From: Molecular evidences for population differentiation and the migration from south to north of Puccinia triticina in eastern ChinaThe division of 11 populations based on different K values (from K = 2 to 4) in the STRUCTURE analysis, and the best value is K = 3, with red, blue, and yellow, representing Cluster 1, Cluster 2, and Cluster 3, respectively. 11 populations are distributed in order from south to north. Single samples are represented by vertical bars, and the colors and proportions of color indicate that samples originated from different clusters. Populations are separated by black vertical linesBack to article page
