Table 1.
Capsicum accessions included in this study.
Fig 1.
Unweighted pair group method (UPGMA) clustering of Capsicum species according to simple sequence repeat (SSR) markers.
‘Height’ represents dissimilarity, derived from ‘dice method’. Bootstrap resampling applied to clusters, represented as percent confidence interval. Numbers following the hyphen indicate replicates.
Fig 2.
Clustering of Capsicum species according to their waxy gene sequences.
Sequences of accessions that begin with “KP” were obtained from NCBI, while those that begin with “PBC” or “VI” were from this experiment. The waxy sequence (gene ID: 101259777) of tomato (Solanum lycopersicum) was used as the root of the tree.
Fig 3.
Reciprocal hybridizations achieved between accessions of Capsicum species.
Direction of arrow represents successful hybridizations in the male-female direction from which fruit was harvested.

Percent germination of selected hybrid seeds 12 weeks after sowing.
Grey indicates unviable seeds.
