“…To the north of Israel (southeast Europe, the south of Ukraine, the North Caucasus region and Dagestan in Russia, and Turkey) virulence frequency on Lr3ka and Lr30 genes varied from intermediate to high level in all relevant years from the late 1990s to 2015. In particular, it was above 90% for both Lr3ka and Lr30 in the North Caucasus and Dagestan (Gultyaeva et al , , , , ); 84% and 92%, respectively, in the south of Ukraine in 2013 (Babayants et al , ); 62% and 54%, respectively, in Turkey in 1999 (McVey et al , ); and virulence on Lr30 was 92% and 100% in Italy and Bulgaria, respectively, in 1998 ( Lr3ka was not tested; Mesterhazy et al , ). The situation appears to be different in the relevant regions to the south of Israel (northeast Africa including Egypt), although less information on infection type reactions on Lr3ka and Lr30 genes is available from there.…”

Leaf rust, caused by the fungus Puccinia triticina, is the most common rust disease of wheat in wheat‐producing areas worldwide. The Israeli population of P. triticina has been consistently monitored since 1993. A total of 784 single urediniospore isolates from Triticum aestivum were analysed during 2000–15. The structure of the pathogen population has changed to a large extent since 2000. The annual populations of P. triticina were separated into two distinct groups, 2000–11 and 2012–15, while populations of 2000–5 and 2006–12 were differentiated to a lesser extent. The change in the population originating from T. aestivum during the period 2000–15 is less significant compared to changes in the 1990s described previously. Diversity within the annual populations of P. triticina was rather stable during the period studied. Three new pathotypes, characterized by virulences on Lr3ka and Lr30 genes, became dominant between 2012 and 2015, while all but one prevailing pathotypes in 2000–11 were avirulent on these two genes. Significant changes in virulence frequencies on a number of Lr genes (Lr2c, Lr3ka, Lr15, Lr21, Lr23, Lr26, Lr30) and pairwise associations of virulences (mainly with Lr2c and Lr26) were registered in 2012–15 or earlier. It is postulated that the composition and pathotype structure of the P. triticina population in Israel is determined by wind‐disseminated urediniospores from neighbouring regions, where the migration of P. triticina from the eastern part of the Mediterranean Sea and from the Horn of Africa seem to have the greatest influence.

“…Изученные изоляты ранее были охарактеризованы по признаку вирулентности (Gultyaeva et al, 2016). Для обозначения фенотипов использована буквенная номенклатура (Long, Kolmer, 1989), основанная на определении вирулентности к пяти группам из двадцати Lr-линий: Lr2a,Lr2c,Lr3а;Lr16,Lr24,Lr26;Lr11,Lr17,Lr30;Lr3bg,Lr14a Lr14b;Lr18,Lr19,Lr20.

The analysis of pathogen intraspecific differentiation is a necessary stage for the development of a strategy of wheat leaf rust resistance breeding. To characterize the structure of the populations, virulence to Thatcher lines with leaf rust resistance genes (TcLr) and microsatellite markers may be used. The purpose of the present research is to study the intraspecific variability of the fungus Puccinia triticina Erikss. on Triticum L. hexaploid species and Aegilops trivialis (Zhuk.) Migusch. et Chak. using SSR-markers. Leaves of Triticum aestivum L., T. compactum Host., T. macha Dekapr. et Menabde, T. petropavlovskyi Udacz. et Migusch., T. spelta L., T. sphaerococcum Perc., T. vavilovii Jakubz. and Ae. tri vialis with uredinia were collected on the experimental field of the Dagestan experiment station of VIR (Derbent) in 2014. For SSR-analysis 109, monopustule isolates previously characterized for virulence to 20 TcLr-lines were used. As a result of 18 microsatellite loci polymorphism analysis, 16 genotypes were identified. Genetic similarity between collections of isolates from the hexaploid types of wheat was significantly higher based on microsatellite markers than based on virulence. Microsatellite analysis confirmed a high similarity between Derbent isolates of P. triticina coming from the hexaploid Triticum species (including isolates from common wheat) and Aegilops trivialis.
