Abstract
In order to analyze the relationship of genetic background of Ribes plants with its susceptibility to the rust fungus,we carried out internal transcribed spacers(ITS)and cross-infection study on eleven Ribes spp.from 7 typ- ical five-needle pine blister rust heavily occurred sites.The results showed that the Ribes plants being easily suscep- tible to the rust spores come from different sites were closely related in the ITS genetic relationship,the rust spores selected preferably the local Ribes spp.as alternate hosts,and the Ribes species which distributed broadly were more susceptible to the rust fungus than the other Ribes species.All the data suggested that the genetic features and geo- graphical distribution of the Ribes determined the susceptibility to the rust fungus.
