Variety traits

Marketability of lettuce

Lactuca sativa L.

A complex indicator of produce suitability for sale, expressed as the share of marketable mass in the total biological yield. It evaluates the conformity of plants to quality standards, morphological characteristics of the variety, and the absence of developmental defects.

In the reference 52 varieties crop Lettuce, where this is mentioned in the description.

The marketability of lettuce is determined by calculating marketable yield, measured in c/ha or kg/m². During evaluation, only the portion of the plants — heads or leaf rosettes — that meets established quality standards and has reached commercial maturity is weighed. Additionally, the marketable yield output is calculated as the percentage ratio of marketable mass to the total biological mass of the harvest.

Marketability criteria include plant conformity to the variety model in terms of size and shape, as well as the absence of damage, diseases, and signs of premature bolting. Important indicators also include the preservation of marketable appearance after harvest and the plant's ability to form a full-fledged rosette under specific growing conditions, whether in soil or hydroponics.

A high marketability index is the primary criterion for the economic utility of a variety, ensuring production profitability. For market supply, varieties with uniform onset of commercial maturity and a prolonged period of shelf life are critically important, as this allows for the maintenance of stable conveyor-belt production.
