Isolation and fine mapping of Rps6: An intermediate host resistance gene in barley to wheat stripe rust [PDF]
, 2016 A plant may be considered a nonhost of a pathogen if all known genotypes of a plant species are resistant to all known isolates of a pathogen species. However, if a small number of genotypes are susceptible to some known isolates of a pathogen species ...
