Between 2002 and 2004, Agroscope FAL Reckenholz and RAC Changins tested four varieties of tall oat-grass (Arrhenatherum elatius L) and four varieties of golden oat-grass (Trisetum flavescens L.) at five and seven experimental sites respectively. The varieties were compared for yield, juvenile development, vigour, disease resistance, winter hardiness and competitive ability. With golden oat-grass the adaptation to higher altitudes was also accounted for. An index value was calculated from the data, allowing for a direct comparison of the tested varieties. According to the results, the new variety of tall oat-grass Arone is recommended. With golden oat-grass, Gunter will be newly added to the «List of Recommended Varieties of Forage Plants».
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.
