The cultivated carrot is believed to originate from Afghanistan before the 900s, as this area is described as the primary centre of greatest carrot diversity (Mackevic 1929), Turkey being proposed as a secondary centre of origin (Banga 1963). The first cultivated carrots exhibited purple or yellow roots. Carrot cultivation spread to Spain in the 1100s via the Middle East and North Africa. In Europe, genetic Purple Chantenay Carrotsimprovement led to a wide variety of cultivars. White and orange-coloured carrots were first described in Western Europe in the early 1600s (Banga 1963). Concomitantly, the Asiatic carrot was developed from the Afghan type and a red type appeared in China and India around the 1700s (Laufer 1919; Shinohara 1984). According to this history, it makes sense to envisage that colour should be considered as a structural factor in carrot germplasm.
