Figure 2From: New microsatellite markers developed from Urochloa humidicola (Poaceae) and cross amplification in different Urochloa speciesa Analysis performed with STRUCTURE 2.3 software using an admixture model with correlated allele frequencies. The clustering profile obtained for K = 6 (b) is displayed and is indicated by different colors. Each of the 34 genotypes is represented by a single column broken into colored segments with lengths proportional to each of the K inferred gene pools. The left-hand scale indicates the membership coefficients (Q) for allocating genotypes into clusters. Genotypes are named according to the annotated numbers listed in Table 3; four major Clusters of individuals were identified, and Clusters are indicated by numbers I-VI. b ΔK values for each K value, calculated according to Evanno et al. [21]. The highest ΔK value corresponds to the optimal K.Back to article page
