Biodiversity of Cav. in rice-growing regions of the south of Russia using PCR method.

The purpose of this research by the way of investigating the molecular genetic structure of a highly variable fungal phytopathogen Cav., to determine effective genes for the development of a strategy for immunogenetic protection against rice blast in conditions of epiphytotic development of the disease in the south of Russia, which would combine high efficacy with both environmental friendliness and resource and energy saving, to ensure country's food security. The knowledge of local pathotype diversity of Cav.
