| Research results and discussions. The resistance of 23 isogenic lines of Bt to severe common
bunt was tested in an artificial infection medium, based on the results in the table, it can be seen that the majority of isogenic lines are resistant to the pathogen Tilletia caries (DC.) Tul. 18 isogenic lines were characterized as highly resistant due to the absence of any symptoms in wheatear grains. They are as follows M84-522 to 530, RB / SEL 1403 (Bt-2), M82-542 to 550, RB / TK 3055 (Bt-4), Red Bobs / Hohenheimer (Bt-5), M82-562 to 570), RB / TK3055 (Bt-7), M78-9496, RB / PI 178210 (White Seed) (Bt-8), M84-597 to 605, RB / CI 7090 (Bt-9), M82-625, SEL M83-162 (Bt-10), Doubi, DW (Bt-14), Carlton, DW (Bt-15), SEL 2092 (Bt-1), SEL1102 (Bt-2), Turkey 1558 (Bt-4), Hohenheime (Bt -5), Rio (Bt-6), R63-6968 (Bt-10), M82-2123 (Bt-8.9.10), P.I. 119333 (M82-2141), BW (Bt-12) and Thwle III.P.I. 181463, BW (Bt-13). Hence Bt-2, Bt-4, Bt-5, Bt-7, Bt-8, Bt-9, Bt-10, Bt-14, Bt-15, Bt-1, Bt-2, Bt-4, Bt We can say that the genes -5, Bt-6, Bt-10, Bt-8.9.10, Bt-12 and Bt-13 are highly effective in Almaty region.

Heines VI (Bt-0) and M84-504 to 510, Red Bobs (Bt-0) were found to be medium soft to common bunt, the incidence of these lines ranged from 15 to 22%. In the case of Almaty region, the line Sel 50077 (Bt-7) can be considered as nonresistant to the pathogen Tilletia caries (DC.) Tul, the incidence of this line was 3 points (Table 1, Figure 1). Figure 1 – The avirulent groups of Bt isogenic lines to Tilletia caries (DC.) Tul. population In the next stage of the study, resistance of 25 domestic winter soft wheat varieties to the pathogen Tilletia caries (DC.) Tul was tested in an artificial environment. Based on the results of the table, 15 wheat varieties (Zhetysu, Nureke, Raminal, Dinara, Egemen-20, Karasai, Reke, Talim, Kyzyl Biday, Naz, Egemen, Mereke 70, Manshyk, Zhalyn and Kazakhstanskaya 25) were highly resistant to common bunt (Table 2, Figure 2). жүктеу/скачать 7.12 Mb.
