Hoffman (24) a These names correspond to those in the Germplasm Resources Information Network (GRIN) database ( Number in parentheses refers to the number of chromosomes. b Plant Introduction (PI) numbers are permanent numbers designated to germplasm accessions maintained at the National Plant Germplasm System (NPGS) in, Iowa, USA. 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 numbers have to be determined they are not duplicate accessions, and that they can be successfully maintained by the USDA. It is not guaranteed these accessions may be assigned a PI number after the assessment period. c ALB (Alternaria Leaf Blight) were recorded 93 days after sowing, which corresponded to harvest time for cultivated accessions. d Area under the disease progress curve (AUDPC) for Alternaria leaf blight (ALB). e Location refers to where the germplasm was collected in the wild. If the accession was obtained through another entity (vendor, genebank, botanic garden), the source is indicated within parenthesis.
