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.

Abstract Background: As rice ( Oryza sativa ) is the staple food of more than half the world’s population, rice production contributes greatly to global food security. Rice blast caused by the fungus M agnaporthe oryzae is a devastating fungal disease of rice, affecting yield and grain quality and resulting in substantial annual economic losses. Because the fungus evolves rapidly,, resistance conferred by most of the single blast race resistance genes is often broken after a few years of intensive agricultural use. Effective resistance breeding in rice therefore requires continual enrichment of the reservoir of resistance genes and alleles. Seed banks represent a rich source of genetic diversity; however, they have not been extensively used to identify novel genes and alleles. Results: We carried out a large-scale screen for novel blast resistance alleles in 1883 rice varieties from major rice producing areas across China. Of these, 107 varieties showed at least moderate resistance to natural infection by rice blast at rice blast nurseries in Enshi and Yichang, Hubei Province. Using sequence-based allele mining to amplify and clone the allelic variants of major rice blast resistance genes at the Pi2/9/gm/zt locus of chromosome 6 from the 107 blast-resistant varieties, we identified 13 novel blast resistance alleles. We then used controlled infections to assess the resistance of rice varieties carrying the novel alleles to 34 single rice blast isolates from Hubei, Guangdong, Jiangsu, Hunan, Jangxi, Sichuan, Heilongjiang, and Fujin Provinces. The varieties identified as being resistant in the nursery trials showed varied disease responses when infected with the single blast isolates, suggesting that the novel Pi2/9/gm/zt alleles vary in their blast resistance spectra. Some of the newly identified alleles have unique single nucleotide polymorphisms (SNPs), insertions, or deletions, in addition to polymorphic residues that are shared between the different alleles. Conclusions: These alleles expand the allelic series of blast resistance genes, enriching the genetic resource for rice blast resistance breeding programs and for studies aimed at deciphering rice–rice blast molecular interactions.
