Seedling tests and field observations conducted during 1951–59 in various regions of Israel, under diverse environmental conditions, have attested to the extremely high resistance of oat varieties possessing the so-called "Canadian" genes to the most prevalent and widespread race 6 of oat stem rust. Seedlings of these varieties inoculated with race 6 become susceptible to this parasite when exposed to 29 °C. for all or an appreciable part of the incubation period. Subjecting of these seedlings to 29 °C. prior to inoculation does not affect their resistance.
