Fig. 2From: Natural variation in genes potentially involved in plant architecture and adaptation in switchgrass (Panicum virgatum L.)STRUCTURE output assuming K = 3 for 372 switchgrass genotypes based on 251 SNPs. Each genotype is represented by a thin vertical line divided into K colored segments representing the individual’s estimated membership probability to each of K clusters (C1, C2 and C3 are in blue, green and red, respectively). Genotypes were grouped by ecotypeBack to article page
