Abstract

Cytogenetic analysis of Iris pumila L. plants from different habitats in Ukraine revealed the intraspecific chromosomal polymorphism. The chromosome number 2n = 32 was established for plants of this species. Root apical meristem of I. pumila shoots of all populations showed a high level of mixoploidy. The differences in the percentage of aneuploid cells and anaphase aberration were found between the sampled populations. The anaphase analysis revealed the level of chromosomal rearrangements that reached 9.2% in some populations.
