Between 2000 and 2002 the Swiss Federal Research Stations for Agroecology and Agriculture (FAL) at Reckenholz in Zurich and for Plant Productions of Changins (RAC) conducted comparative trials with 22 varieties of tall fescue and four varieties of meadow foxtail at five experimental sites. Based on measurements and observations of yield, persistence, competitive ability, disease resistance and digestibility of organic matter (DOM) and, additionally in tall fescue, fineness of leaves an index-value was calculated allowing for an accurate comparison of the varieties. The following varieties of tall fescue have been newly accepted in the Swiss «List of recommended varieties of forage plants»: Belfine, Molva, Barolex and Dulcia. In meadow foxtail, the new selection G 9438 has been added to the list of recommended varieties.

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.
