From 2010 to 2012, the Agroscope Reckenholz-Tänikon ART and Agroscope Changins-Wädenswil ACW research stations tested 31 varieties of cocksfoot in the field at seven sites for their suitability for cultivation. In addition to the 17 new varieties, the previously-recommended varieties were re-tested. The characteristics evaluated were yield, vigour, juvenile development, competitive ability, persistence, winter-hardiness, resistance to leaf diseases, and digestible organic-matter content. Of the early varieties, «Berta» can now be recommended, having distinguished itself by its excellent digestibility. Almost thirty years after its inclusion, «Loke» has been deleted from the List of Recommended Varieties of Forage Plants owing to unsatisfactory results. Of the late varieties, «Barlegro» has been newly recommended. The best of all late varieties tested, this new variety shone in particular in terms of digestibility, juvenile development, vigour, and competitive ability. The results for the formerly recommended varieties «Accord» and «Foly» no longer satisfy the requirements for recommendation, for which reason they are to be removed from the list.

Five Merlot clones bred in Switzerland are currently being distributed by the certification sector. A multiyear trial conducted by Agroscope in Gudo (Canton of Ticino) has made it possible to compare them with French and Italian reference clones and to highlight their very good performances.
Arbuscular mycorrhizal fungi are important for healthy soils and crops. A pan-European study shows that plant-protection products adversely affect these fungi, reducing their ability to supply plants with phosphorus via their roots.
Birdsfoot trefoil and sainfoin are used in mixtures for perennial hay meadows and for tannin-containing fodder. Agroscope is adding two new cultivars of birdsfoot trefoil to the ‘List of Recommended Varieties of Forage Plants’, whilst there is no change in the case of sainfoin.
