Using resistant cultivars is an effective method in management Zymoseptoria tritici Blotch and Fusarium Head Blight of wheat. This study was conducted to identify new sources of resistance to these diseases among a large number of Iranian cultivars and new wheat genotypes. The genotypes were cultivated in an augment design in the research farm of Aliabad Katoul Agricultural School. Artificial contamination of the genotypes were done using spreading infected leaves and inoculating with a pathogenic fungal spore suspension. Response of the genotypes to disease-causing were noted. Cluster analysis categorized genotypes into seven groups. Third and fourth groups were allocated as resistant and sensitive, respectively. Genotypes No 3 (Hirmand), 6, 10, 12, 13 (Golestan), 38 (Aftab), 40 (ghabous), 44 (Pishtaz), 51, 52 (shoosh), 59 (Pastor), 64, 68, 73 (Sepahan), 87, 92, 95, 97, 99, 110, 116, 127 (Line 7) and local check cultivar (Ehsan) were classified at group three (resistant). This group had the lowest area under the disease progress curve and showed high resistance to disease. Resistant genotypes identified in this study can be used in breeding programs for pyramiding resistance genes or using backcrossing method.
