During 2001-2003,the reactions of 23 wheat advanced lines and commercial cultivars were evaluated in the field trials against important fungal diseases, yellow rust (Puccinia striiformis), septoria leaf blotch, (Septoria tritici) and common crown and root rot (Bipolaris sorokiniana and Fusarium culmorum). Results indicated that lines M-78-1, M78-12, M-78-13, M-78-14, M-78-19 and cv. Shiraz were moderately resistant and lines M-78-5, M-78-6, M-78-15, M-78-17 and cvs. Darab 2 and Roshan were moderately susceptible to yellow rust. The rest were susceptible. These scores were different from those previously recorded for these lines and cultivars. These changes seem to be due to the appearance of the new race, 166E134A+. In case of septoria leaf blotch, most genotypes were susceptible except line M-78-6 which was moderately susceptible. In a field trial, this line produced the highest yield and 1000 kernel weight under high incidence of both diseases. This is a good point for recommending M-78-6 for planting in highly infested area. All cultivars except M-78-1 were highly susceptible to common root rot pathogens.
