Variety traits

Rice tolerance

Oryza sativa L.

Rice tolerance to abiotic stresses, such as salinity and drought, is evaluated through the ratio of seedling biomass under stress conditions to control values and the identification of the Saltol genetic locus.

In the reference 33 varieties crop Rice, where this is mentioned in the description.

The evaluation of rice salinity tolerance is conducted using laboratory and field methods. Laboratory screening is based on comparing the biomass of 10-day-old seedlings in saline solutions and distilled water, where values of 30–50% of the control correspond to moderate resistance, and those above 70% correspond to high resistance. At the genetic level, the key marker for salt tolerance is the Saltol locus on chromosome 1, which is identified using PCR analysis.

The introduction of tolerant cultivars into rice farming practice ensures yield stability, potentially preventing losses of up to 2 tons per hectare on adverse soils. Breeding for this trait contributes to improving the overall adaptability of the crop, as mechanisms of ion homeostasis and antioxidant defense often provide complex resistance to drought and extreme temperatures.
