The paper presents the results of the evaluation of susceptibility to the smut of domestic and foreign proso millet collections in the conditions of the dry steppe zone of Northern Kazakhstan. According to the defeat of the smut pathogen among the varieties of the domestic collection, three groups were formed: 1) 40-56%; 56- 72% and 72-88%. According to these data, highly stable forms have not been identified, which indicates the need to search for resistance donors for the breeding process. Based on the results of screening for resistance to the phytopathogen, stable genotypes were identified among the USDA collection: PI 170587 (SARI,
Turkey); PI 531419 (PROSOS, Kenya); PI 649372 (Index Seminum 295, France, Bas-Rhin); Ames 28191 (Kazakhstan); Ames 10555 (I.Pm. 547, India); PI 173002 (DARI, Turkey); PI 179380 (IPM 1010, Turkey); PI 204905 (IPM 1040, Turkey); PI 207501 (IPM 690, Afghanistan); PI 163298 (CHINI, India); PI 173750 (IPM 990, Turkey); PI 177015 (IPM 1001, Turkey); VIR collection: K-8503, K-1685, K9645, K-10213, K-9580, carrying resistance genes to local races of the pathogen. And also according to the results of the stability assessment, among the samples of the foreign collection, the forms which manifested dw-reaction were found - PI 346944 (Polyploid), PI 367683 (WHITE FRENCH STRN.8567; Australia), PI 427247 (Nepal), PI 427250 (Nepal) , PI 433381 (Vishenutu; Taivan), PI 463090 (PV 14; India); PI 463243 (MS 1501; India); PI 649373 (TU-86-42-03; Turkey). With the inoculation of these samples by native races of the smut, strong bushiness was observed, without the formation of a productive panicle. This proves that there is a race of 6A in the local population and a Sp 1 resistance gene in the genotype. The above samples can be used as a donor for resistance to a dusty head in millet
breeding. The above samples can be used as a resistance donor to a smut in proso millet selection.
