Physiologic specialization of wheat leaf rust (Puccinia triticina Eriks.) in the Czech Republic in 2001-2004

Original language description

In 2001-2004 virulence in 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 intotal) were obtained from different parts of the Czech Republic. Resistance genes Lr9 and Lr19 were effective to all tested isolates as in previous years. Unlike in 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 as in previous years, followed by races 61, 2, 12SaBa, 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

Fyziologické specializace rzi pšeničné (Puccinia triticina Eriks.) v České republice v letech 2001-2004

Czech description

V letech 2001-2004 byla studována virulence v populaci rzi pšeničné na téměř izogenních liniích s geny rezistence Lr1, Lr2a, Lr2b, Lr2c, Lr3a, Lr9, Lr10, Lr11, Lr15, Lr17, Lr19, Lr21, Lr23, Lr24, Lr26 and Lr28. Vzorky rzi pšeničné (celkem 180) byly získány z různých částí České repupliky. Geny resistence Lr9 a Lr19 byly účinné ke všem získaným izolátům. Relativně vysokou efektivitu měl i gen Lr1, Lr2a, Lr24, Lr28 and Lr2b.
