Powdery mildew, caused by Blumeria graminis f. sp. tritici (Bgt), is one of the most demaging diseases of wheat in all regions where it is grown and can lead to serious yield losses. Blumeria gr. f. sp. tritici is an obligate and host-specific fungal pathogen that attacks all aerial parts of the plant. Inoculation of plants with each of the races was carried out at the "second leaf" stage. The type of infection was reported after 8-10 days. Data from the study showed that of the 71 breeding materials studied, 46 were susceptible to all six races of the pathogen. Twenty-five breeding materials showed resistance to one or more races. Line "10/131-55-56" is distinguished by a resistant reaction to all six races included in the study, and lines "14/53-1" and "14/53-10" have a resistant reaction to five of the races of the pathogen. Eight of the materials tested (Santorin, 18/10-11, 18/87-61, 14/52-92, 14/52-104, 14/15-42, 14/52-43 and 14/53-75) have the same reaction type as the differentiating cultivars Asosan/8xCc and Khapli, which contain the Pm 3a and Pm 4a genes, respectively. The reaction of lines DH 974/8-2-30, DH 995-100, (09)232-65 GT 9-232 and varieties Alkantra 19, Chudomira and Kasidy is like that of differentiating varieties Disponent with resistance gene Pm 8 and Weihenstephen M1 with the Pm 4b gene. The cultivars "Gabrio 21", "Forkali" and "08/147-32 (Zara GT 8-14)" have a response type that does not correspond to any of the known genes included in the study.
