Some citrus species and cultivars with attractive appearance of fruits and leaves have been used for ornamental purposes. Some of them have small fruits and plant size and mixed color of leaves or fruits. Here, we report a new lemon genotype with potential use for ornamental purposes. This genotype was obtained exposing 'Kutdiken' lemon cultivar budwood to gamma irradiation. This cultivar is widely grown in Turkey because of its high yield and good quality fruits. Fruits of the new genotype have attractive appearance with vertical brown lines and brown point heaps. Differences of fruit rind of this genotype have originated from mutation(s) caused by gamma irradiation.
