| description | The current paper has considered the challenge of breeding of rice lines adapted to the climatic conditions of the Southern Federal District of Russia by pyramiding a complex of Pi-1, Pi-2, Pi-33, Pi-ta and Pi-b rice blast resistance genes which is efficient in the southern part of Russia. The control of the resistance genes present in the breeding material was carried out using a marker-associated selection (MAS). The purpose of the current study was to identify the Pi-1, Pi-2, Pi-33, Pi-ta, and Pi-b rice blast resistance genes in the rice samples developed in the laboratory of rice breeding and seed production of the FSBSI “Agricultural Research Center “Donskoy” to identify valuable genotypes. The screening of 689 breeding samples of rice resulted in identification of the allelic state of the Pi-1, Pi-2, Pi-33, Pi-ta and Pi-b rice blast resistance genes, and the genotypes with functional alleles of these genes and their combinations. There were identified 19 breeding samples of rice possessing a combination of 4 functional alleles of rice blast resistance genes in various combinations. The identified rice samples are valuable genetic material and are recommended to use as the sources of rice blast resistance in the breeding process. |
