Supplementary Data 1

Supplementary data 1. The 83 accessions of Daucus, and one accession of related genus examined in this study, the new identification and the locality information. (a) These names correspond to those in the Germplasm Resources Information Network (GRIN) database. The 14 accessions designated with an asterisk sign were not analyzed using morphological characters, but DNA sequences only. The 38 accessions designated with a plus sign were only analyzed using 11 morphological mericarp characters (results not shown in this study). DNA sequences of the 31 accessions designated with a pound sign were obtained from Arbizu et al. (2014a). The 25 accessions designated with a square sign were used in Bayesian concordance analysis. The 2n chromosome numbers are those known for the species, not the individual accessions, according to Grzebelus et al. (2011) and IPCN Chromosome Reports (http://www.tropicos.org/Project/IPCN). (b) Plant Introduction (PI) numbers are permanent numbers designated to germplasm accessions maintained at the National Plant Germplasm System (NPGS) in Ames, Iowa, USA. Ames numbers are assigned for carrots and other Apiaceae in the NPGS temporarily to newly acquired germplasm until passport data of an accession and taxonomy is verified. Also, accessions with Ames numbers have to be determined they are not duplicate accession, and that they can be successfully maintained. These accessions may or may not be assigned a PI number after the assessment period. (c) Location refers to where the germplasm was collected in the wild, while source refers to germplasm obtained through another entity such as a market vendor or genebank.
