Meiotic associations were studied at metaphase I in PMCs of autotetraploid and autotriploid plants of Russian wildrye (Psathyrostachys juncea). Autoploidy without the presence or action of the bivalentization system was demonstrated. In light of the meiotic behaviors in these autoploids, breeding strategies for Psathyrostachys juncea were suggested. Possible uses of these materials are described.
