Fig. 2From: Genome-wide SNP discovery and population structure analysis in pepper (Capsicum annuum) using genotyping by sequencingEstimate of genetic diversity in 222 C. annuum accessions using 32,950 SNP markers. a Bar-plot describing the population structure estimated by the Bayesian clustering. Each individual is represented by a thin horizontal line, which is partitioned into K coloured segments whose length is proportional to the estimated membership coefficient (q). The population was divided into three (K = 3) groups according to the most informative K value (see Additional file 2: Figure S5). Dashed black lines separate individuals in different clusters. b Dendrogram plot derived from the non-parametric hierarchical clustering. D2 indicates the allele sharing distance. Black continuous lines separate individuals of different sub-populations. The population was divided into three (K = 3) groups according to the most informative K value (see Additional file 2: Figure S6)Back to article page
