The distribution of mitotic chromosome numbers and changes in the meiotic chromosome pairing in the vegetative progenies of Agropyron repens cv Purdue somaclones were analyzed. Mitotic chromosome variability showed an increase at both cell (SC1-3 somaclones) and plant (SC2) level. Nevertheless, from the progenies of the somaclone SC2, a stable hipoploid clone with a chromosome number of 2n = 38 was selected. The numbers of aneuploid cells in the root tips of vegetative clones also showed an increase. In the analysis of meiotic chromosome pairing, a shift towards the appearance of multivalents (quadrivalents, hexavalents, octovalents) was observed.
