The most significant crop among the leafy vegetables is Lactuca sativa L., most commonly
known as lettuce. Lettuce, which is grown as a one-year cool climate vegetable belonging to
the Compositae family, has been registered in our country as ıceberg, cos, lollo, and butterhead
lettuce types. But different types of lettuces registered in recent years, in addition to the number
of leaf divisions, thickness and size. The shift in lettuce types that have been authorized for
registration through 2022 has been thoroughly investigated with the help of this study. The
registered lettuces were also examined in the study in terms of some characteristics, their
dendrograms were taken out, and an attempt was made to determine their relatedness to one
another. As a result, these descriptors are effective analytical tools for researching the intricate
morphological variability of this species and interactions between the varieties.
