An overview is given on the world-wide occurrence and frequency of mating type A2 ofPhytophthora infestans, on ploidy levels, increased virulence and fitness of the pathogen population in Germany and the Netherlands. Experiments on the survival of oospores in the open showed that these may survive in Europe until the next growing season. The resistance reaction of the differential set of R-genes used to determine virulence of races ofP. infestans is found to vary by differential clone and test method. Work has been started to come to a more homogenous differential set. The impact of oospores and the new population ofP. infestans on epidemiology and hence on disease forecasting is unknown. |
