This paper presents the results from molecular genetic studies on breeding material of domestic and foreign sugar beet hybrids for the presence of resistance genes to root-knot nematode, rhizomania, and powdery mildew. Testing of plants was carried out using the polymerase chain reaction method. The genes R6m-1, Rz1 and Rz2, and Pm were identified with the help of five single-chain RAPD and four allele-specific primers. As a result of molecular screening of the sugar beet cultivar samples, the presence of these resistance genes was revealed.
