Tetrax is one of the first tetraploid meadow fescues, listed in Switzerland. Plots or fields with Tetrax are less dense and the dry matter yield, on average, is about 6 % lower than that of the best diploid varieties. But this will balanced out by a significantly higher digestibility. On average, the digestible organic matter of Tetrax is 20 g/kg higher than one of the best diploid varieties. Tetrax also has a very good resistance to leaf diseases, a rapid juvenile development and a good winter condition. These positive characteristics helped Tetrax to achieve the clearly best overall index in the official variety trials 2008-10 in Switzerland (Suter et al. 2011).
