“…In the Czech Republic virulence in the rust population has been studied since the sixties of the last century, first on the standard differential cultivars ( Johnston & Browder 1966) and on an additional differential Salzmünder Bartweizen (Lr26). Results of these studies carried out in the years 1966-2001 were summarized by Hanzalová and Bartoš (2014). Later on determination of virulence was based on reactions of leaf rust isolates on a set of Thatcher near-isogenic lines (NILs) possessing Lr genes.…”

Plant Breed., 50: 288-292.The research report presents a summary of wheat leaf rust virulence surveys in the Czech Republic from 2002 to 2011. Determination of virulence was based on infection types on Thatcher near-isogenic lines (NILs) with the resistance genes Lr1, Lr2a, Lr2b, Lr2c, Lr3a, Lr9, Lr10, Lr11, Lr13, Lr15, Lr17, Lr19, Lr21, Lr23, Lr24, Lr26 and Lr28, respectively. Virulence for Lr9 and Lr 19 occurred only sporadically in the investigated period. On average, virulence for Lr2a, Lr2b, Lr24 and Lr28 was low. The highest frequency of virulence was found for Lr3a, Lr10, Lr11, Lr13, Lr15, Lr17, Lr21, Lr23 and Lr26. During the investigation period we recorded a shift from prevailing virulence for Lr2c and avirulence for Lr1 to avirulence for aLr2c and virulence for Lr1. Ther virulences in the leaf rust population were compared with matching resistance genes in the registered wheat cultivars. The most frequent resistance gene was Lr37, while the genes Lr3a and Lr26 were less frequent.

“…McCallum et al (2011) found that the most common races in Canada during 2008 growing season were TDBJ (23.6%), TDBG (23.1%) and MLDS (18.9%). Moreover, Hanzalova and Bartos (2014) found that the leaf rust races 14, 77, 61, 53 and 2 were dominated in Czechoslovakia/Czech Republic in the years 1966-2001. Finally, Anjum et al (2014 identified the two leaf rust races 12-9 (93R37-1) and 77-11 (125R28) in India during 2009 growing season.…”

“…Moreover, as the prevalence of races in a specific season and region depends on the type of wheat cultivars grown and to some extent on the predominant environmental conditions, especially temperature (Roelfs et al, 1992). Also, due to the long-distance dispersal of leaf rust races (intercontinental migration) (Burdon and Silk, 1997;Kolmer, 2005;Hanzalova and Bartos, 2014). This process led to the shifts in the genetic structure of the recipient pathogen population, especially when such pathogen cannot survive the summer in the country (Saari, 1976;Burdon and Silk, 1997).…”

Wheat leaf rust caused by Puccinia triticina Eriks. is a common disease in Egypt and worldwide. Survey of wheat leaf rust samples and identification of physiological races using twenty single Lr genes are very important in describing virulence pattern variation, geographical distribution of leaf rust pathotypes and how its change in response to host selection. Variability in population of the causal organism is annually determined using samples collected from wheat growing areas in Egypt for three growing seasons that is

Collections of Puccinia triticina obtained from wheat fields and breeding plots in the Great Plains, Ohio River Valley, and southeastern states, were tested for virulence in 2014 in order to determine the virulence of the wheat leaf rust pathogen population in the United States. Single uredinial isolates (380 total) were derived from the collections and tested for virulence phenotype on 20 lines of Thatcher wheat that are near-isogenic for leaf rust resistance genes. In 2014, 55 virulence phenotypes were described in the United States. Virulence phenotypes MBTNB, TBBGS, and TCRKG were the three most common phenotypes. Phenotypes MBTNB and TCRKG are both virulent to Lr11, and TCRKG is also virulent to Lr18 and Lr26. MBTNB and TCRKG were most common in the soft red winter wheat region of the southeastern states and the Ohio Valley. Phenotype TBBGS is virulent to Lr39, which is present in the hard red winter wheat cultivars, and Lr21, which is present in the hard red spring wheat cultivars. Isolates with virulence to Lr11, Lr18, and Lr26 were most common in the southeastern states and Ohio Valley region. Isolates with virulence to Lr21 and Lr39 were most common in the hard red wheat region of the southern and northern Great Plains.
