Eriksson (31, pp. 340,341; 27, p. 249) also found in his experiments that often those varieties most susceptible to P. glumarum were most resistant to P. graminis and P. dispersa. In Victoria in the season of 1803-04 McAlpine tried a number of varieties sent to him by Eriksson from Sweden, and the results he obtained showed well the differences in susceptibility of the same varieties to different rusts. Though the varieties were recom- mended as being quite resistant to P. (jlmnarum in Sweden, they were badly affected with P. rubigo-vera in Victoria. The matter was dis- cussed in detail by McAlpine before the Fourth Intercolonial Rust-in- Wheat Conference of Australia»(52, p. 27), and also by Eriksson in an.
