Abstract
The snow mould ( Microdochium nivale ) resistance of 13 winter rye cultivars was studied in field trials and in three different laboratory tests: snow mould chamber tests, enzymatic assay tests and leaf segment tests. On the basis of the results, it is suggested that both the field trials and the snow mould chamber tests describe more the general winterhardiness of plants involved in the survival of the crown tissue of plants during prolonged incubation under the snow cover, than the snow mould resistance. The results from the enzymatic assay and the leaf segment tests indicate that there are other, more specialized snow mould resistance mechanisms in the plant that act also at the single leaf level. At least some of these resistance reactions seem to be induced by the lytic enzymes secreted by M. nivale.
