Why carrot?

Carrot [Daucus carota L. subsp. sativus (Hoffm.) Arcang.] is a widely grown vegetable crop that is valuable not only as a cash crop but also as an excellent source of vitamin A, an important contributor to nutrition, and vitamins K and B6. The wild carrot, Daucus carota, is native to Europe and southwestern Asia.

What we achieved


  • 86 seed samples of one carrot wild relative (Daucus carota) were collected from eight countries: Armenia, Azerbaijan, Cyprus, Georgia, Italy, Nepal, Pakistan and Portugal.

Pre-breeding and evaluation

  • Carrot seed from the United States Department of Agriculture (USDA) carrot breeding program was tested in field trials in Bangladesh, India, Pakistan, Thailand, and Taiwan.
  • Five pre-bred lines were identified as suitable for expanded production and are candidates for release based on general performance.
  • Seven pre-bred lines with stress tolerance and high yield were identified as suitable for expanded production, and four are candidates for release.
  • Several lines were found to have high levels of nematode resistance, Alternaria resistance and abiotic stress tolerance and will be included in breeding programs in Asia.
  • Female and male farmers were trained in carrot seed production and those in Bangladesh, India, Pakistan and Thailand indicated an interest and capability to produce carrot seed after the training.

Carrot key collections, materials and data

Carrot collections

  • The largest carrot collection is conserved at the USDA NPGS, Ames, Iowa, USA.
  • The Genesys PGR database also includes information about carrot accessions in genebanks worldwide

Pre-breeding materials 

  • All pre-breeding materials and promising ILs have been conserved in the USDA National Plant Germplasm System (NPGS) genebank in Ames, Iowa, USA, and are freely available to institutions and individuals for testing and use. Access to unreleased germplasm can be made available under a Material Transfer Agreement with USDA.
  • 93 carrot genotypes comprising 53 open pollinated (OP) landraces, five commercial OP lines, 26 USDA breeding lines and nine commercial F1 hybrids have been conserved at the WorldVeg genebank, Tainan City, Taiwan.
