This review paper covers the results of tissue culture and biotechnology of rye (Secale cereale L.) published between 1990 and 2000. The following subjects were raised: somatic embryogenesis, haploid production, intergenetic hybridisation and transformation. Upon conclusion of all the results published to date, we may say that the progress of biotechnology in the case of rye is very limited in comparison to other cereals. However, a lot of work and efforts were involved to obtain the aforementioned result. Taking into account the progress in plant genetics and molecular biology, the authors deeply believe that the New Millennium will bring a brake-through in rye biotechnology.
