Diversity structure of the 224 Musa accessions based on 16 SSR loci generated by Structure program using the admixture model from matrix derived from Analysis I. The 21 groups (sub-populations) are represented by distinct colors. Each column represents one accession that can be fractionated into segments, whose size is proportional to the estimated membershipfractions (q) in k clusters. Genomic constitutions were based on morphological descriptors (Table 1; Additional file 1: Table S1). Correlation values (r) with the alternative Analysis II used are shown in parenthesis. C: cultivated; W: wild; H: hybrid.
