Key directions of scientific research:

  • Cytogenomics of bread crops; studying the structural and functional variability of genomes at molecular and cellular levels at distant hybridization, polyploidy, and inbreeding;
  • Studying of microevolutionary differentiation mechanisms of polyploid bread crop species;
  • Experimental transformation of the genetic structure of cereal crops (rye, wheat, triticale, and secalotriticum) using chromosome engineering techniques;
  • Chromosomal and molecular marking of the new gene pool of tetraploid and hybrid rye (CMS), recombinant tetraploid and hexaploid forms of triticale and secalotriticum; marker assisted selection (MAS).
