Virulence characteristics of a wheat leaf rust pathogen population in five agroclimatic zones of the North Caucasus

Virulence of a Puccinia triticina population is studied in five agroclimatic zones of the North Caucasus. Frequencies of virulence genes are described and trends of intrapopulation changes in the genetic structure of the fungus are identified. The percentage of phenotypes with a different number of...

Description
Summary:Virulence of a Puccinia triticina population is studied in five agroclimatic zones of the North Caucasus. Frequencies of virulence genes are described and trends of intrapopulation changes in the genetic structure of the fungus are identified. The percentage of phenotypes with a different number of virulence genes in each zone of the region is shown.
