This trait determines the duration of the growing season from sowing to technical maturity, ranging from 130 to over 200 days. The maturity group directly influences the morphology of the pseudo-stem, frost resistance, and the storage quality of the produce.

crop Leek,
where this is mentioned in the description.
Leek varieties are classified into early-maturing with a growing season of 130–150 days, mid-maturing — 150–180 days, and late-maturing or winter varieties, the ripening period of which exceeds 180–200 days. This indicator determines the cultivation strategy depending on the agro-climatic conditions of the region.
The morphological features of the plant depend on the maturity group: early varieties form a tall pseudo-stem with lower density, while late varieties are characterized by a short but dense stem and high cold tolerance. Late-maturing varieties have the capacity for long-term storage and overwintering, whereas early-maturing ones are intended for obtaining produce in a short time frame and do not possess high storage potential.
