The ability of cabbage hybrids to maintain productivity when exposed to biotic pathogens or abiotic stressors. It manifests as intermediate disease resistance or the preservation of commercial quality under field physiological stress.

In cabbage breeding, tolerance is understood as intermediate resistance (IR) to pathogens such as Fusarium wilt (Foc) or black rot (Xcc). Under high disease pressure, plants may show symptoms of infection but retain the ability to produce a marketable yield, unlike varieties with complete immunity.
Tolerance to physiological stresses, particularly head splitting, is evaluated in the field at biological maturity by calculating the percentage of damaged plants. Ecological adaptability is determined using statistical methods by calculating the coefficients of variation in head weight during trials under various environmental conditions.
