Winter survival of perennial ryegrass ( Lolium perenne L.) depends mainly on the plant resistance to low freezing temperature and to snow mould fungi ( Microdochium nivale ). Field evaluation of these plant characters gave irreproducible results. A comparison of field trials with laboratory tests pointed to the close correlation between the yield level of examined varieties and strains and their resistance to Microdochium nivale and frost. A lack of correlation between snow mould resistance and frost tolerance was shown.
