Tomato Tolerance

Solanum lycopersicum L.

The ability of a tomato genotype to maintain productivity and quality under biotic or abiotic stress, despite the development of symptoms.

In the reference 234 varieties crop Tomato, where this is mentioned in the description.

Tomato tolerance is defined by the plant's ability to sustain growth and fruit production at an economically acceptable level in the presence of a pathogen or adverse environmental conditions. Unlike resistance, where genetic mechanisms suppress pathogen development, a tolerant genotype endures stress with minimal loss of biomass and yield.

Assessment of the trait is based on a comparative analysis of the yield of infected versus healthy control plants, as well as biometric indices: stem growth rates, root system development, and pollen quality retention. In phytopathology, tolerant specimens are often classified as having low susceptibility.

The use of tolerant varieties ensures stable harvesting of marketable produce during epiphytotics, for example, in cases of Fusarium wilt or powdery mildew. In breeding practice, tolerance is considered a key agronomic and biological characteristic for crop protection in high-inoculum environments.
