Karyotype Analyses of the Genus Matthiola (Brassicaceae) in Turkey

In the present paper, karyotype analyses are reported for 12 taxa of Matthiola from Turkey. Matthiola trojana Dirmenci, Satil & Ttimen, M odoratissima (Pall.) R.Br., M anchonifolia Hub.-Mor., M montana Boiss., M fruticulosa (L.) Maire ssp. fruticulosa and M ovatifolia (Boiss.) Boiss. counted 2n=12 chromosomes, and M incana (L.) R.Br., M longipetala (Vent.) DC. ssp. bicornis (Sibth. et Smith) P. W. Ball, M longipetala (Vent.) DC. ssp. longipetala, M longipetala (Vent.) DC. ssp. pumilio (Sibth. & Smith) P. W. Ball, M sinuata (L.) R.Br., and M tricuspidata (L.) R.Br. showed 2n=14 chromosomes. The idiograms and karyomorphometric data obtained by using Image Analysis System (Bs200Pro). The chromosome number of M montana was determined for the first time. Also, karyotype asymmetry index such as M-CA, CVCL and CVCL were measured for the reconstruction of karyological relationships.
