| Stem rust or black rust is one of the most important fungal diseases that widely affect wheat yield and quality at different sites of the world. So, the selection of resistant genetic materials to stem rust in breeding programs is necessary. In this study, 24 winter wheat genotypes including eight varieties and 16 elite lines were evaluated at the adult plant and seedling stages using a randomized complete block design under the influence of a local stem rust race TTTT. Disease indices including the type of infection, the severity of infection, coefficient of infection, the area under the disease progress curve (AUDPC(, the relative area under the disease progress curve (rAUDPC), and genotype reaction were recorded. Significant differences were observed among the genotypes for all disease indices. Based on all indices, MV-17 and C-98-17 were resistant and C-98-14, C-98-9, Bolany, and Morocco were susceptible. High and positive correlations among field type of infection, the severity of infection, coefficient of infection, AUDPC, rAUDPC, genotype reaction at the field, greenhouse type of infection, and genotype reaction at the greenhouse were observed. Based on the cluster analysis by Ward’s method and discriminant analysis, at the adult plant stage, all the genotypes were classified into four groups (resistant, moderately resistant, moderately susceptible, and susceptible), and at the seedling stage, genotypes were classified into two groups (resistant and susceptible). Therefore, these resistant genotypes are recommended to be used in breeding programs for stem rust resistance. | ||
