“…Response of each genotype to bunt disease was evaluated according to Dodoff and Todorova, (19) modified method where R= Resistant (Infection percent 0-10%), I= Intermediate resistant (Infection Percent 11-30%), S= Susceptible (Infection Percent 31-50%), and HS = highly susceptible (infection percent 51-100%) (9). All the data were statistically analyzed using analyses of variance (ANOVA).…”

“…The current study was conducted to identify the probability of presence of five known Bt resistance genes in 42 registered and released bread wheat and two Triticale cultivars using three specific SSR markers GWM7433, XGWM 114, and XGWM 264 compared to the stock culture of Bt8, Bt9, Bt10, Bt11 and Bt12 that exhibits high levels of resistance in the fields to the available pathogen population under Sulaimani conditions (7,9). Results revealed that only two bread wheat cultivars -Charmo and Hsadpossess the resistance gene Bt9 at 296bp, and only one bread wheat cultivar -Buhoth 10possesses the known resistance gene Bt12 at 175bp, while no any of the tested cultivars contain the known resistance genes Bt8, Bt10, and Bt11 (Figure 2).…”

This study was conducted to identify resistance sources in the Iraqi wheat cultivars using pathological and molecular approaches. Results revealed that forty-four reeleased wheat cultivars were divided into four groups according to their mean infection percentage to common bunt disease. Resistant group consists of wheat cultivars Farris 1, Ashur, Tamuz 3, AlMadian, AlBaraka, Latiffiya, and Rabia. The mean infection percentage of this group ranged from 0.28-3.98% and significantly was higher than that of all other groups during two growing seasons. Moderately resistant cultivars included cv’s Bura, Iratom, Charmo, Maaroof, and AlRasheed with mean infection range of 10.39- 21.10%. The majority of the tested cultivars (63%) explored high susceptibility to the disease (52.14-91.97%) while the mean infection of the susceptible group ranged from 31.51% in Buhoth 22 to 47.47% in Wafia. Molecular analysis using SSR markers GWM7433, XGWM114, and XGWM264 revealed that Charmo and Hsad- possess the resistance gene Bt9 at 296bp, while Buhoth 10 possesses the known resistance gene Bt12 at 175bp. All the tested cultivars not contain the known resistance genes Bt8, Bt10, and Bt11. The high resistance level of the resistant group could be attributed to the presence of additional known resistance Bt genes or other unidentified resistance genes.
