- Abstract
Variability of winter wheat cultivars infection by fungus Puccinia recondita f. sp. tritici was analysed in the years 2010, 2011 and 2013. The study the results of post-registration trials conducted in four locations: Naroczyce, Zybiszów, Tarnów and Kondratowice. The degree of infection of wheat cultivars was evaluated on the three upper leaves of plants nine-degree scale (where: 9 - healthy plants; 1 - 100% plants infected). The following cultivars: Figure, Natula, Ostroga, Mulan, Bamberska, Askalon, Szmaragd and Muszelka were assessed. There were significant differences in the occurrence of severity of leaf rust in the years of research and locations. In Zybiszów location regardless of the year of the study the wheat cultivars were infected the most by leaf rust as compared to other locations. Analysis of variance showed a significant interaction of the cultivars with the years and the cultivars with the locations. The cultivar Figura was characterized by a high susceptibility to infection by fungus P. recondita f. sp. tritici, while the cultivar Ostroga by an increased resistance.
