Between 1995 and 1997, 38 varieties of red clover and 24 of meadow fescue have been evaluated in a comparative variety test program. The criterias looked at were properties as yielding ability, competitive ability, resistance to diseases and persistence. Based on the achieved results, the following varieties are newly considered for the <<List of Recommended Varieties of forage Plants>): long duration red clover Corvus (2n), Pica (2n), Larus (4n) Astur (4n), short duration red clover Tedi (4n), Maro (4n), Sigord (4n), meadow fescue Pradel and Cosmolit.

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.
