Evolutionary relationships among 73 Allium accessions based on a Maximum likelihood analysis of the nrITS region. Bootstrap support (BS; %) from the ML analysis is given above the branches. The posterior probability (PP) value from the Bayesian analysis is given below the branches. For simplicity, strongly supported branches (both BS > 95% and PP > 0.95) are denoted by an asterisk (*). Accessions of A. erimomeli (red), A. occultum (blue), and A. pilosum (green) are highlighted in colour. For population codes of newly sequenced accessions, see Suppl. material 2. For details about the other accessions, see Vojtěchová et al. (2024), Duchoslav et al. (2026a, 2026b), and Nikolopoulos et al. (2026).
