Abstract :The polyphyletic genus Paronychia includes about 110 species that are distributed throughout the world except in the southern of Africa and Asia. Türkiye is one of the most important distribution centers of genus Paronychia represented by 29 species. The basic and diploid chromosome numbers were recorded in 22 species (26 taxa) of Turkish Paronychia. The aim of this study is to report for the first time the karyological data of P. dudleyi and P. pontica. The chromosome number and karyotype formula were 2n = 4x = 36m in P. dudleyi and 2n = 2x = 18m in P. pontica. The karyotype asymmetry values (especially intrachromosomal) were quite low. As a result, the new karyological data were recorded: (i) first report of the basic and diploid chromosome numbers, (ii) ploidy levels of 2x and 4x, (iii) first detailed chromosomal data, (iv) the most symmetrical karyotypes.
Keywords : Paronychia, kromozom, karyotip asimetrisi, poliploidi
