From 2007 through 2009 the Agroscope Reckenholz-Tänikon ART und Agroscope Changins-Wädenswil ACW research stations tested in total 39 varieties of Italian ryegrass, including 29 new breeds, in comparative variety trials at five locations. The evaluation of the varieties was based on systematic observations of yield, vigour, juvenile development, competitive ability, winter hardiness, resistance to leaf diseases and bacterial wilt and of digestible organic matter. Four new breeds attained results allowing for registration on the “List of Recommended Varieties of Forage Plants”: Morunga, LI 0035, Elvis and LI 0455, of which only the three former can be recommended. LI 0455 cannot be added to the list for the time being because it is not eligible for trade in Switzerland yet. The formerly recommended variety Abercomo did not achieve results allowing for future recommendation and will be omitted from the list.
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.
