Fennel Maturity Group

Foeniculum vulgare Mill.

A classification characteristic of fennel that determines the duration of the growing season from emergence to technical or biological maturity. Values depend on the intended use of the crop — vegetable or oilseed.

In the reference 59 varieties crop Fennel, where this is mentioned in the description.

For vegetable fennel, the indicator of maturity is the formation of a marketable bulb, whereas for oilseed and medicinal types, it is the onset of waxy or full maturity of the fruits. The maturity group is measured in days from the moment of emergence and is a determining factor when selecting a variety and planning harvest.

Early-maturing oilseed fennel varieties ripen in 110 days, while vegetable types take 40–55 days. Mid-maturing forms require 140–175 days for the oilseed type and 75–78 days for the vegetable type, while late-maturing varieties are characterized by a growing period ranging from 180 to 230 days or more.

This trait directly affects raw material quality, including the accumulation dynamics of essential oils such as anethole and fenchone. For vegetable varieties, the correct selection of a maturity group is critical to prevent premature bolting and to ensure the production of a high-quality marketable bulb before the development of the flower stalk.
