Cultivation and Breeding:
The first evidence of the breeding of Kohlrabi comes from mid-Europe and goes back to the 16th century. The forerunner of Kohlrabi was probably the so-called Pompeian kale of the ancient Romans, or the marrow-stemmed kale (var. medullosa), in which the shoot axis is thickened in the middle.
The varieties available today include early, summer and autumn Kohlrabi, with white-green to blue-purple coloured tuber skins.
Breeding aims:
High yields (number per unit area), strength, and shoot stability, along with delicate texture are of importance.
A short development time is important for early Kohlrabi.
