Description
The article presents results of studies on the intraspecific structure of the population of blast causative agent using sets of tester varieties from International Rice Research Institute - IRRI. The differentiation of the fungus population on tester varieties is the most progressive, since it allows one to determine the virulence genotypes of races of pathogens and identify the resistance genes of rice plants effective for them. The work has studied the diversity of blast causative agent in released rice varieties by morphological and cultural traits. Currently, in the world, the resistance of rice plants to blast is becoming one of the important indicators of the competitiveness of varieties. The basis for the successful rice breeding for resistance to blast is the availability of source material with a fairly wide spectrum and a high level of resistance. Resistance donors are selected based on the identification of genes that control this trait in rice
