Based on modern technologies of molecular DNA-markers, blast disease–resistance genes (Pi-ta, Pi-b, Pi-1, Pi-2, and Pi-33) were introgressed and pyramided into domestic rice varieties to give them longterm disease resistance. For that purpose, this case study uses SSR-markers closely linked to these genes, as well as intragenic markers of genes Pi-ta and Pi-b. Multiplex PCR systems were created for simultaneous identification of two resistance genes in the hybrid progeny for the following combinations: Pi-1 + Pi-2, Pi-ta + Pi-b, Pi-ta + Pi-33.
