“…The race spectrum described in our virulence survey is similar to that in Hungary where also races 61, 12 and 77 are widespread together with race 20 (MANNINGER 2000). A similar race spectrum has also been determined in Slovakia.…”

Abstract:In 2001-2004 virulence of the wheat leaf rust population in the Czech Republic was studied on Thatcher near-isogenic lines with Lr1, Lr2a, Lr2b, Lr2c, Lr3a, Lr9, Lr10, Lr11, Lr15, Lr17, Lr19, Lr21, Lr23, Lr24, Lr26 and Lr28. Samples of leaf rust (180 in total) were obtained from different parts of the Czech Republic.Resistance genes Lr9 and Lr19 were effective to all tested isolates like in the previous years. Unlike the previous years virulence on Lr24 and Lr28 was observed. Relatively effective were also Lr1, Lr2a, Lr24, Lr28 and Lr2b. Other Lr genes were defeated by the majority of the tested samples. Our results transformed to the numbers of physiologic races indicate that race 61SaBa prevailed like in the previous years, followed by races 61, 2, 12Sa-Ba, 2SaBa, 14, 77SaBa, 12, 57, 6, 53, 53SaBa, 77, and 14SaBa. Twenty-one winter wheat cultivars registered in 2001-2004 were tested with 8 leaf rust isolates. Out of them 15 showed resistance at least to one rust isolate. High resistance recorded in field trials for cvs Batis and Ilias, which were susceptible to all tested rust isolates at the seedling stage, demonstrates the importance of field (partial) resistance.

“…Other above mentioned triticale cultivars though they were resistant to three pathotypes at the seedling stage, they were susceptible at adult stage. Manninger (2006) found distinct differences in the virulence of leaf rust isolates from triticale compared to virulence of isolates from wheat. In our experiments virulence to all tested lr NILs except lr19 was observed in isolates from wheat and in triticale except lr19 and lr24.…”

“…Mikhailova et al (2009) selected 17 leaf rust resistant triticale accessions out of 416 tested triticale from the Vavilov All-Russian Research Institute of Plant Industry. In Hungary Manninger (2006) tested eight winter triticale both at seedling and at adult stage. Cultivars Presto, Tricolor, Disco, GK Bogo, Kitaro, Pongo were resistant at the seedling stage to three pathotypes of wheat leaf rust and susceptible only to one pathotype.…”

Abstract:Reactions of winter triticale cultivars mostly from central Europe to recent and old leaf rust isolates were tested in the greenhouse. In one trial 20 cultivars were tested with 8 leaf rust isolates, collected recently from official wheat and triticale trials in the Czech Republic and Slovakia. In another trial 15 cultivars were tested with 6 old leaf rust isolates, used to identify leaf rust resistance genes in wheat. The cultivars Cando, Hortenso and Tricolor, registered in the Czech Republic, were resistant to the majority of the recent isolates. The Hungarian cultivar Tatra was resistant to all the recent isolates. The old leaf rust isolates were virulent only to a few of the triticale cultivars. Randomly selected isolates from wheat and triticale were tested on triticale cultivars and on Thatcher near isogenic lines with different lr genes. On average, leaf rust isolates from triticale were virulent to a higher number of triticale cultivars than isolates collected from wheat and vice versa.

“…In Hungary, 13 races were identified among 70 bread wheat isolates using 15 Thatcher near-isogenic lines, and 2 races came from 12 triticale isolates (Manninger 2006). Most races from bread wheat were virulent to Lr2b, Lr2c, Lr3, Lr11, Lr17a and Lr26, but the races from triticale were virulent only to Lr2b, Lr2c and Lr11.…”

Global status of wheat leaf rust caused by Puccinia triticina

et al. 2011

View full text Add to dashboard Cite

Leaf rust caused by Puccinia triticina is the most common and widely distributed of the three wheat rusts. Losses from leaf rust are usually less damaging than those from stem rust and stripe rust, but leaf rust causes greater annual losses due to its more frequent and widespread occurrence. Yield losses from leaf rust are mostly due to reductions in kernel weight. Many laboratories worldwide conduct leaf rust surveys and virulence analyses. Most currently important races (pathotypes) have either evolved through mutations in existing populations or migrated from other, often unknown, areas. Several leaf rust resistance genes are cataloged, and high levels of slow rusting adult plant resistance are available in high yielding CIMMYT wheats. This paper summarizes the importance of leaf rust in the main wheat production areas as reflected by yield losses, the complexity of virulence variation in pathogen populations, the role cultivars with racespecific resistance play in pathogen evolution, and the control measures currently practiced in various regions of the world.
