Abstract :Centaurea L. insert ignore into journalissuearticles values(Asteraceae); is one of the largest genera in Turkey. The chromosome number and morphology of 8 taxa belonging to the genus Centaurea were investigated using an image analysis system. Among these taxa, the chromosome numbers were as follows: 2n = 18 in C. cariensis Boiss. subsp. niveotomentosa insert ignore into journalissuearticles values(Hub.-Mor.); Wagenitz, C. lycaonica Boiss. & Heldr., C. virgata Lam., and C. polyclada DC.; 2n = 24 in C. cyanus L.; 2n = 36 in C. virgata and C. cariensis Boiss. subsp. cariensis: 2n = 40 in C. urvillei DC. subsp. urvillei; 2n = 54 in C. tuzgoluensis Aytaç & H.Duman. In 5 taxa mixoploidy was observed insert ignore into journalissuearticles values(C. lycaonica, C. urvillei subsp. urvillei, C. cariensis subsp. cariensis, C. virgata, and C. tuzgoluensis);. Based on karyotypic data for this genus, 3 basic chromosome numbers in Centaurea taxa were observed insert ignore into journalissuearticles values(x = 9, 10, and 12);. Furthermore, ideograms are given for all the Centaurea taxa studied.
