Abstract :In this study, some cytological characters of orchardgrass were examined naturally growing in Erzurum. Plants assessed for their chromosome number were tetraploid insert ignore into journalissuearticles values(2n=28);. In metaphase I stage the most prevalent pairing was bivalents insert ignore into journalissuearticles values(avg. 8.37);. This was followed by quadrivalent insert ignore into journalissuearticles values(avg. 2.81);, univalent insert ignore into journalissuearticles values(avg. 0.04); and trivalent insert ignore into journalissuearticles values(avg. 0.015); pairings. All combinations of bivalents and quadrivalents were recorded. In most of anaphase l cells examined chromosomes distribution to poles were even insert ignore into journalissuearticles values(14: l4);, however some cells had laggings and bridges. In addition, 95. 17% of observed tetrads had no micronucleus.
