Two new red clover cultivars, CORVUS and PICA, of the persistent “Mattenklee” type are being released in Switzerland. They have been selected for being less aggressive in mixtures. Their first year yield is slightly lower than that of the known “Mattenklee” cultivars. However, they have an excellent level of resistance against stem nematodes, powdery mildew and other important diseases, and they are as persistent as most of the known “Mattenklee” varieties. Plot trials with standard mixtures confirmed that the new varieties are less dominant in mixtures. In summer of the first full harvest year, their part in the mixed canopy was smaller than that of a standard “Mattenklee” cultivar. This tendency continued for PICA in the second year. However, in the second harvest year, both CORVUS and PICA behaved more like a persistent “Mattenklee” than a regular, short-lived type of red clover, which limits their use in grass-white clover mixtures. In conclusion, the new varieties are the most suitable for the “Mattenklee” mixtures, in particular for the new recipe SM 310.
Tall oat grass and golden oat grass are typical hay-meadow grasses that are also suitable for forage mixtures. Of the four tall and three golden oat grass varieties tested, only one new variety of tall oat grass is likely to make it onto the List of Recommended Varieties.

FiBL and Agroscope investigated bread wheat varieties to determine their yield and quality stability. The results show that the choice of variety must be adapted to the site and that high yield potential does not go hand-in-hand with a high protein content.
Adapted and high-yielding varieties of forage plants are important for Switzerland as a grassland country. Hybrid ryegrass is a versatile forage grass that, thanks to breeding advances, has become even more persistent, disease-resistant and high-yielding over the past 30 years.
