GREENHOUSE TESTS TO COMPARE EUROPEAN AND BELTSVILLE ISOLATES OF PERONOSPORA TABACINA
Abstract
Of the tobaccos used to differentiate a European and the Beltsville isolate of Peronospora tabacina, sporulation occurred on Nicotiana goodspeedii with the European but not with the Beltsville isolate. This situation was reversed on Bel 62-502-1 (N. tabacum selection). Watersoluble germination inhibitors are present in both fungus isolates. Germination of the two isolates in response to temperature is similar. The European may sporulate more profusely on a susceptible host than does the Beltsville isolate; it also has a narrower temperature range for sporulation.
