Stem rust in recent years has acquired an epiphytotic character, causing significant economic damage for wheat production in some parts of Kazakhstan. On the basis of a race composition study of the stem rust populations collected in 2016-2017 in South-Eastern and northern regions of Kazakhstan were identified. The race differentiation of stem rust using a tester set of 6 Sr genes differentiator lines was carried out. In different conditions of Kazakhstan, the Sr22 and Sr25/Lr19 gene sources are effective. As a result of PCR analysis, the Sr22 gene was found in 5 lines of 6 samples taken for the study: Line C-19SB, Lutescens 7-04-4, Lutescens 220-03-45, GA961662-1-7/TAM107, Line D 25 77. Sr25/Lr19 is a carrier of sources: Lutescens 220-03-45, Advance, Line D 25 77. The Sr22 and Sr25/Lr19 gene was Lutescens 220-03-45 and Line D 25 77. These sources are recommended for inclusion in the breeding process for developing stem rust resistant varieties in the region.
