According to a study conducted in 2011–2012, Puccinia recondita populations from Ulyanovsk and Bezenchuk share one geographic range of leaf rust variety formation and dispersal. At the same time, a significant similarity between the structures of the Middle Volga population and of populations from the North Caucasus and Northwestern Russia was shown. Clones… (More)
Molecular STS markers J13, Gb, and J09 were used for screening wheat (Triticum aestivum L.) accessions previously found to possess leaf-rust resistance genes according to test crosses or phytopathological tests. Specific amplification products were detected in all accessions assumed to possess the Lr9 gene, in nine of ten accessions with the conjectured… (More)
Induction of resistance under the effect of benzimidazole is shown by using the method of infecting intact plants and leaf segments of 27 near-isogenic lines of cultivar Thatcher carrying various leaf rust resistance Lr genes. It is shown that induction depends on the particular resistance gene, pathogen clone, and benzimidazole concentration.
Wheat samples described in literature as resistant to septoria glume blotch were assessed for their response to inoculation with Septoria nodorum Berk. Three days after inoculation with the causal agent, samples Klein Titan (k-41772), Mian Jang (k-61568), Walter (k-54585), Reisler (k-59505), Rempart (k-59493), PIN/BOW (k-62838), MN81330 (k-60785), Frondoso… (More)
Of 153 samples reported to be resistant to leaf rust (Puccinia recondita Rob. ex. Desm.), only 70 were not affected by a complex P. recondita population. According to phytopathological tests (inoculation with test clones), 14 samples possessed the Lr19 gene; 36, the Lr24 gene; 1, the Lr41 gene; and 19 presumably had the Lr9 gene. The presence of these genes… (More)
Leaf rust resistance was studied in barley accessions from the world collection of the Vavilov All-Russia Institute of Plant Industry. Most accessions described as highly resistant in the literature proved susceptible. High resistance at the juvenile stage was observed only for the cultivars Henry, Cebada Capa, Forrajera Klein, and Scarlet. Hybrid analysis… (More)
Having studied genetic control of juvenile resistance to diseases in Aegilops tauschii Coss. samples from the VIR collection, we identified one dominant gene for effective resistance to leaf rust Lr41, seven recessive genes for resistance to septoriosis, and two recessive genes for resistance to dark brown leaf spot blotch.
Using the inoculation of both the intact plants of Triticum L. and leaf segments of the plant in the presence of kinetin with the complex population of Puccinia triticina Erikss, the genotype-dependent induction of resistance by kinetin was found. It was proved that this induction depends on the concrete gene of resistance of the plant and on the genotype… (More)
According to the literature data, G-genome tetraploid species Triticum timopheevii and T. araraticum are highly resistant (immune) to powdery mildew. Unde-epephytoty of the disease, not a single pustule was found on the leaves of any T. timopheevii accessions or on most of the T. araraticum accessions. Infection of the spikes of accessions of the given… (More)
Wheat samples described in literature as resistant to septoria glume blotch were assessed for their response to inoculation with Septoria nodorum Berk. Three days after inoculation with the infectious agent, samples Klein Titan (k-41772), Mian Jang (k-61568), Walter (k-54585), Reisler (k-59505), Rempart (k-59493), PIN/BOW (k-62838), MN81330 (k-60785),… (More)
