In this experiment, we assessed the production of dry forage, number of plants and growth differences in eight tetraploid and fourteen diploid varieties of red clover grown in mixture with grasses. The highest production of forage for both harvest years was achieved by the Czech varieties Spurt and Amos and by the Swiss variety Milvus. The lowest forage production was recorded in both years in the Swedish one-cut varieties Betty, Jesper and SW Torun. In the second production year, the most yielding was the German variety Lucrum, followed by the Czech varieties Spurt and Amos. The highest cover in the third production year was reached by the Swiss variety Artus (87.8%) while the lowest cover was recorded in the Austrian variety Reichersberger Neu (40.0%). The tetraploid varieties exhibited significantly lower contents of dry matter but their productivity and persistence did not differ from diploids. Very suitable for long-term use thus appear the Swiss varieties of Mattenklee type (Artus, Milvus), the German variety Lucrum and the Czech varieties Amos, Spurt and Start.
