<i>Phytophthora infestans</i> (Mont.) de Bary — eine ständige Herausforderung seit 140 Jahren

Available data have been evaluated on the reaction of potato differentials to over 5000 Phytophthora infestans isolates, collected in various parts of the world. The differentials were able to identify up to 11 virulence factors in P. infestans. The isolates differed in virulence expression, depending on the isolate and testing conditions. All 11 virulence factors were found in both ‘old’ and ‘new’P. infestans populations. The resistance of individual differentials was not overcome with equal frequency. The resistance of differentials R5, R8 and R9 was overcome least frequently. This may be due to instability of expression of the respective virulence factors in P. infestans and/or the kind of resistance present in the differentials. Whatever the reason, such resistance may possibly be used in breeding potato cultivars with durable resistance to P. infestans.
