The susceptibility/resistance to the potato virus M (PVM) and the intensity of PVM biosynthesis in the meristemic clones of the same cultivar as well as in the meristemic clones regenerated from the meristems operated from different parts of the same plant (apical and lateral buds of shoot, immatural bud of flower) were studied. The named resistance characteristics to PVM in 27 meristemic clones of 4 potato cultivars (Premiere, Eba, Kondor, Vigri) was compared. The differences in the degree of susceptibility and intensity of virus biosynthesis in meristemic clones of the same cultivar, i.e. of genetically homogeneous material, were established. The most resistant meristemic clone-virus combinations for each cultivar studied were selected to get the prospective initial material for seed potato production. The highest relative resistance to PVM was found in meristemic clones Eba 1000, Kondor H, Premiere 356, and Vigri 918
