Abstract

Synchytrium endobioticum (Schilb.) Perc., the causal agent of potato wart disease, is one of the
most important harmful organisms on potato (Solanum
tuberosum L.). It is listed in the EPPO A2 list as a pest recommended for
regulation. The disease occurs in many European countries in local limited areas. So
far, more than 40 pathotypes of Synchytrium endobioticum are
currently described in Europe, from which, the most important pathotypes are 1(D1), 2(G1), 6(O1), 8(F1) and 18(T1). The pathotypes 6(O1), 18(T1) and 38(Nev) of S. endobioticum were found previously in Turkey. In the following years, the disease
became an increasing problem for Turkey in potato production and marketing. A total
3.432,5 ha area was reported as infested by the fungus in the Central Anatolia
Region in 2014. In order to determine the local pathotypes, soil samples
were collected from two different fields infested with the fungus in Derinkuyu
county of Nevşehir city in June 2014. Two different experiments were carried
out, a bioassay according to the Glynne-Lemmerzahl method and a pot test. S. endobioticum pathotypes present in
the two fields in which the experiments conducted were determined as pathotypes
2(G1) and 18(T1). This paper is the first report of pathotype 2 in Turkey.

Türkiye’de Synchytrium endobioticum’un yeni bir patotipi: Patotip 2

Abstract

Patates siğil
hastalığı etmeni Synchytrium endobioticum
(Schilb.) Perc. patateste (Solanum tuberosum
L.) zarar yapan en önemli organizmalardan biridir. Etmen EPPO’da A2 listesi
zararlısı olarak yer almaktadır. Hastalık, sınırlı alanlarda birçok Avrupa
ülkesinde görülmektedir. Patates siğil hastalığının şimdiye kadar 40’dan fazla
patotipi tanımlanmış olup, Avrupa’daki en önemli patotipler 1(D1), 2(G1), 6(O1), 8(F1) ve 18(T1) olarak
belirlenmiştir. Türkiye’de 6(O1), 18(T1) ve 38(Nev) numaralı patotipler tespit
edilmiştir. Türkiye’de patates üretimi ve pazarlaması için hastalık artan bir
sorun haline gelmiştir. Orta Anadolu’da 2014 yılında hastalıkla bulaşık alan
3.432,5 ha olarak rapor edilmiştir. Bu çalışmada yerel patotipleri belirlemek amacıyla
2014 yılında Nevşehir ili Derinkuyu ilçesinde iki farklı bulaşık alandan toprak
örnekleri alınmıştır. Patotiplerin belirlenmesi için Glynne-Lemmerzahl metodu ve
saksı testi ile iki farklı araştırma yürütülmüştür. Bu çalışmaların yürütüldüğü
iki farklı tarlada bulunan S. endobioticum
patotipleri 2(G1) ve 18(T1) olarak belirlenmiştir. Bu çalışma Türkiye'de
patotip 2'nin belirlenmesinin ilk raporudur.
