Tolerance to Fusarium wilt is assessed by bioassay methods, where the key criteria are the rate of symptom development, vascular browning, and the severity of root and stem damage. Due to the lack of a direct correlation between morphological traits and the actual degree of infection, molecular diagnostic methods are used to identify pathogen races.
When assessing the impact of abiotic factors, tolerance is defined as the plant's ability to maintain biomass and growth rates under increased UV-B radiation or low soil temperatures. In agronomic practice, qualitative scales of high, moderate, and low tolerance are used, which are established based on the results of trials in pathogen-infested fields.
