Karyotype of Matthiola Trojana T.Dirmenci, F.Satil and G.Tumen (Brassicaceae), endemic to Turkey

Abstract

Matthiola trojana T.Dirmenci, F. Satil & G.Tu¨men is an endemic species belonging to the family Brassicaceae. In this research, chromosome number and morphology were determined in this species. Somatic chromosome number was counted as 2n=12. The karyotype consisted of four pairs of metacentric chromosomes and two pairs of submetacentric chromosomes. Chromosome length varied from 2.44Y4.27 mm. A karyogram and idiogram were drawn based on centromeric index and arranged in order of decreasing size.
