Variability of Synchytrium endobioticum in the Carpathian region of Ukraine¹

Abstract

Research Station on Plant Quarantine, V. Boyani, Novoselitsa District, Chemivtsy Region (Ukraine)The appearance of aggressive pathotypes of Synchytriurn endobioiicurn in the Carpathian area of Ukraine is reviewed. An analysis is made of the factors that favoured their appearance in this area. Possibilities for distinguishing the pathotypes by characters other than their behaviour on differential cultivars are considered.

History of potato wart disease in Europe – a proposal for harmonisation in defining pathotypes

“…In 1973, however, potato wart disease was rediscovered in a field in Ter Apelkanaal, province of Groningen, on a Potocˇek et al (1991), Melnik (1998) and Stachewicz and Langerfeld (1998) Melnik and Malakhanova (1998), the outbreak of this pathotype occurred at the site in South Bohemia where the loss of resistance to pathotype 1(D1) was first observed in 1940. h Later identified as pathotype 2(G1). i Later identified as pathotype 6(O1). )…”

Introduction to the European Phytosanitary Conference on Potato and other arable crops organised by EPPO and the Ukrainian Scientific Research Plant Quarantine Station

“…Since the first report of biological specialisation in the potato wart pathogen Synchytrium endobioticum , numerous pathotypes different from the originally introduced pathotype 1(D1) have been reported. In the past, different codes have been assigned to the same pathotype, for example the pathotype found in Trannroda, Germany was known as pathotype 18 (Langerfeld, 1984), and as pathotype 19 (Melnik & Malakhanova, 1998). We recently tabulated all pathotypes known from literature, and subsequently coded these uniquely as a combination of numbers and letters (Baayen et al ., 2006).…”
