Karyotype Analysis of Five <i>Iris</i> L. (Iridaceae) Species from Turkey

The chromosome numbers and karyotypes of five species the genus Iris distributed in Turkey were analyzed. These taxa are I. aucheri (Baker) Sealy, reticulata var. M. Bieb., persica L., peshmeniana Güner & T. Hall, sarii Schott ex Baker. Two them (I. sari peshmeniana) endemic Turkey. studied determeined as 2n=18 persica), 2n=20 sari), 2n=24 aucheri), 2n=36 reticulata). Haploid lengths varied from 53.45 µm persica) to 130.78 reticulata) among species. Karyotype analysis indicated that generally have median (m), submedian (sm), subterminal (st) chromosomes. In addition, only has two terminal (T) pairs. karyotype was determined for first time.
