Their viability was evaluated through colouration with tetrazolium bromide. The distribution of oospores in the different classes of colouration was similar to that found in other &lt;em&gt;Phytophthora&lt;/em&gt; species (homothallic and heterothallic): most of the oospores stained purple, which corresponds to spores in dormancy. In order to produce single-oospore cultures, a method was developed to separate oospores from mycelium and chlamydospores. Germination of oospores was observed in 110, 250, 350 and 500-d-old cultures at a low proportion. Microsatellite marker analyses on oospore progenies revealed that the oospores resulted from hybridisation. More than 50 oospore progenies were characterised in terms of mating type, aggressiveness on &lt;em&gt;Rhododendron&lt;/em&gt; leaves, and growth rate on two different media. The results are discussed in the context of pest risk analysis.&lt;/p&gt;</style></abstract></record></records></xml>
