title: [Molecular polymorphism of viral dsRNA of yeast Saccharomyces paradoxus].
abstract: An analysis of 53 strains of yeast Saccharomyces paradoxus (YSP) of different geographic origins enabled us, for the first time, to find viral double-stranded RNA (L and M fractions) in YSP and to study natural polymorphism. As in the cultured Scerevisiae, the size of L dsRNA was constant (4.5 kb). The size of minor M dsRNA varied from 1.5 to 2.4 k.b. In YSP, we determined 7 types of M dsRNA (M1-M7), which were not connected with the source of isolation or geographic origin of the host strains.
