| Popis: | Extended Abstract Introduction and Objective: Fusarium head blight disease is one of the most important and destructive diseases of wheat in hot and humid climates, which, in addition to reducing yield, causes the accumulation of mycotoxins in the grain, which is dangerous for humans and animals. Passive resistance against Fusarium includes many morphological and phenological traits such as plant height, flowering time, heading time, number of spikes and spike density, which help to escape the disease or create a kind of resistance to Fusarium head rot disease. The purpose of this study was to compare the studied genotypes with respect to Fusarium head blight disease and to estimate the simple and canonical correlation between morphological traits and disease resistance traits. Materials and Methods: In order to evaluate 92 improved and native genotypes of Iranian bread wheat against Fusarium head blight in two crop years (2019-2022), experiments were conducted in the form of a randomized complete block design in the farm of Gorgan University of Agricultural Sciences and Natural Resources. Morphological traits measured included plant height (PH), spike length (SL), and number of seeds per spike (TSS), and agronomic traits measured included heading time (DTH) and flowering time (DTF). Disease traits were: disease incidence (INC), disease severity (SEV), Fusarium damaged kernels (FDK), FHBdx index and ISK. Results: For all disease-related traits and morphophenological traits, a significant difference (p |
