Variety traits
Lettuce maturity group
Lactuca sativa L.
A trait determining the duration of the period from emergence to technical maturity, classifying varieties into early-maturing (40–45 days), mid-maturing (50–60 days), and late-maturing (70–80 days or more).
In the reference 589 varieties crop Lettuce, where this is mentioned in the description.
For lettuce, the maturity group is measured by the number of days from seedling emergence to the stage of reaching market quality suitable for harvesting. Professional classification includes early-maturing varieties with a maturation period of 40–45 days, mid-maturing varieties — 50–60 days, and late-maturing varieties, which require 70–80 days or more.
The trait is closely related to the plant's response to photoperiod and temperature. Under long-day conditions and high temperatures, early-maturing varieties are more prone to bolting, which leads to leaf coarsening and the development of bitterness. The selection of a maturity group is decisive for organizing sequential production, selecting varieties for a specific seasonal rotation, and choosing the cultivation method, such as direct seeding or transplanting.
