Variety traits

Maturity Group — Kale

Brassica oleracea L. (Curly kale Group)

The maturity classification of kale is based on the number of days from emergence to technical maturity, ranging from 30 to 85 days or more.

In the reference 39 varieties crop Curly kale, where this is mentioned in the description.

The maturation period of kale is measured by the number of calendar days from emergence to the onset of commercial utility. Early-maturing varieties and types for baby leaf harvest reach technical maturity in 25–55 days, while late-maturing varieties require 70–85 days or more to form full-sized leaves.

The maturity trait determines the harvesting technology and seasonal production plan. Late-maturing varieties possess pronounced cold tolerance and are capable of maintaining quality for a longer period during the autumn, while exposure to low temperatures promotes sugar accumulation and improves the taste characteristics of the produce.
