Carrot tolerance

Daucus carota L.

The ability of carrots to withstand the impact of biotic and abiotic stresses while maintaining viability and productivity, with polygenic control of the trait.

In the reference 38 varieties crop Carrot, where this is mentioned in the description.

In the context of carrots, tolerance characterizes the ability of plants to withstand fungal pathogens of the genera Alternaria and Fusarium, as well as to endure abiotic stresses, including drought, salinity, and temperature fluctuations. Unlike monogenic resistance, this trait is polygenically controlled and ensures crop stability under adverse conditions, making it possible to prevent losses that can reach 70% when affected by Alternaria or Fusarium blights.

Tolerance assessment is based on a complex of methods, including work with infectious backgrounds to evaluate the infection of seedlings and mature plants. Physiological methods include measuring the activity of antioxidant systems, chlorophyll content, and the accumulation of reactive oxygen species, while morphological studies are aimed at examining root system development. For large-scale breeding programs, scoring scales are used to assess the response of cultivars, which contributes to improving the marketability of root crops and their storability.
