Culture varieties of diploid meadow fescue are extensively used as forage plant in Europe and North America (Caputa, 1967). After the discovery of colchicine as a polyploidy effect producer, researches on polyploidy in many plant species were started. Many studies on meadow fescue by using colchicine have also been carried out (Simonsen, 1975; Easton, 1977; Sugiyama et al., 1979). Tetraploid plant rate, obtained by colchicine treatment, showed differences according to plant species and varieties. Ahloowalia (1967) and Sağsöz (1982) applied colchicine treatment of 0.2% to different varieties of perennial ryegrass at different tempreratures and obtained different results according to different treatments and varieties.
