This study was carried out in 2020 to determine the light fastness in dyeing cotton fabrics to test the juglone values in the content of domestic and foreign walnut cultivars as well as the use of these cultivars in natural dyeing. According to the results of the study, the light fastness test results obtained after dyeing the dyestuffs obtained from domestic and foreign cultivars of Juglans regia L. walnut species on cotton fabrics were calculated with the lowest 2 values in Serr and Şen 2 walnut cultivars, while the highest 3 were Maraş 18, Şebin, Fernette, and Fernor cultivars. J. regia juglone analysis results obtained from domestic and foreign cultivars of walnut species, from lowest to highest, were determined in Şen 2, Maraş 18, Fernette, Şebin, Maraş 12, Pedro, Serr, Sundland, Bilecik, Chandler, Franquette and Fernor cultivars, respectively. In addition, according to the results of the percentage similarity analysis, in which the similarities between the juglone contents of domestic and foreign walnut cultivars were calculated, it was determined that domestic and foreign cultivars were generally grouped among themselves and these groups had higher similarities among themselves. When the tested juglone amounts of domestic and foreign walnut cultivars included in the experiment were compared statistically, it was found that Fernor (0.2595) and Franquette (0.2581) cultivars were not statistically different, but together with Chandler (0.2538), the juglone amounts of these cultivars were statistically significantly different between almost all cultivars.
