[Pollen development in the anthers of several cereal strains and hybrids during cultivation in vitro].
In order to induce androgenesis in vitro anthers of some cereals were cultivated. The highest number of proembryos was obtained in the hybrid Triticale in F3 generation on Blayder's medium supplemented with 3 and 12% sucrose. Proembryos represented multi-nuclear and multicellular formations which stagnated at the globular stage of development. Origin of roots from calluses was not accompanied by formation of buds. There was no formation of embryos from pollen grains in case of lines Triticum aestivum and Secale cereale.
