Abstract

Aim. To define the features of resistance at the cultivars-carriers of a translocation 1AL/1RS in conditions of Right-bank Forest-steppe of Ukraine to a local population of wheat leaf rust. Methods. Field, laboratory, comparative, analytical. Results. A diversity in exhibiting of resistance at carriers of the wheat-rye translocation 1AL/1RS to the effects of a local population of leaf rust pathogen of wheat in the conditions of Right-bank Forest-steppe of Ukraine is established. Varieties Nekota, Century, Monolog, Smuglyanka, Spasivka are donors of stable resistance. Variety Knyaginya Olga – a source of stable moderate resistance. Varieties Amigo, Colombia and Slavna can be a sources of changeable resistance with noncritical (tolerant) defeat plants at epiphytotic years. Conclusions. The expression of genes of 1AL/1RS translocation depends on the level of infection load. When epiphytotics it fully does not provide the resistance of some varieties. The presence of the background translocation 1AL/1RS of other effective resistant genes increases the resistance of varieties and can provide high resistance and even immunity in the years of epiphytoties. It is necessary to consider such features at attraction of varieties in the breeding process, aimed on resistance to local population of leaf rust.

Keywords: wheat-rye translocation, sources of resistance, wheat, leaf rust.
