SUMMARY. The achievements of modern biotechnology can significantly improve traditional plant breeding. The use of molecular co-dominant markers significantly reduces the amount of breeding material and facilitates selection of genotypes with desirable genes in a homozygous state. The systems of molecular marking of agronomically important simple and quantitative traits with the help of monolocus- and multiloci markers have been developed. The number of markers of type and rate of development, storage protein genes, Wx-gene, short stem genes, and others have been created and validated in SPBC NAAS. Developed in the SPBC technology of DNA-typing for the varieties identification and registration is of great importance for systematization of germplasm sources and protection of breeders rights.
