Cultivars/ Varieties of Carrot
Varieties or carrot are classified on the basis of shape of root and temperature response to flowering. There is carrot varieties such as long rooted, half- long rooted and short stump rooted. On the basis of temperature requirement, carrots are classified as temperate or European and tropical or Asiatic. The temperate varieties are biennial and require low temperature (4 – 8- 10 0 C) treatment for flowering to colour. These do not produce seeds in planes e.g. Nantes, Danvres Half Long etc. the tropical cultivars do not require any low temperature treatment for flowering. They produce flowers and seed in plains of high temperature.
