Earliness, morphological and agronomic characters and grain quality were studied in 123 European landraces and old cultivars of winter wheat in three-year field experiments. Simultaneously, HMW Glu-alleles were identified in these cultivars by means of SDS-PAGE. The gluten patterns themselves were not a sufficient tool for geographic characterisation of cultivars. The composition of Glu-alleles influenced the earliness of cultivars. Spike length was positively affected by allele 1 at 1A and number of spikelets per spike by alleles 2+12 at 1D chromosome. Allele 2* was also associated with lower grain weight per spike. Crude protein content was decreased in cultivars where GS at 1A locus was absent (0). The value of gluten index was considerably higher (59.2) in cultivars bearing allelic combination 5+10 at 1D. A number of alleles affected the values of SDS micro-sedimentation test.
