Identification of pathotypes of Synchytrium endobioticum found in infested fields in Turkey

Pathotypes of four isolates of Synchytrium endobioticum collected from the infested areas of Turkey were determined using Glynne–Lemmerzahl and Spieckermann test methods. Two isolates (Ordu 1 and Nevşehir 1) were tested by the Glynne–Lemmerzahl method in Germany. Ordu 1 was assigned as pathotype 1(D1) whereas the other isolate gave different results in 2 years of testing [pathotype 6(O1) or 18(T1)]. Two other isolates (Nevşehir 2 and Nevşehir 3) were tested using the Spieckermann method in Netherlands. Neither of these last two isolates tested were found to belong to the pathotypes known from Western Europe. The isolates Nevşehir 2 and Nevşehir 3 were given a new, unique code: 38 (Nevşehir).
