title: [Polyploid hybrids of industrial yeast races and the prospects for using them in production].
abstract: The ploidity of the parent forms, hybrids, and two industrial yeast races was studied by determining the content of DNA per cell, the ratios during allel splitting, the dimensions and volumes of the cells. The triploid nature of the baker's race 14--2 and some hybrids was found (for example, the productive hybrid 112 obtained by crossing the distillery and baker's races). The results obtained suggest the possibility to apply the techniques of hybridization and polyploidy for selecting productive yeast strains.
