Variety traits
Triticum aestivum L.
The ability of a soft wheat cultivar to maintain productivity or viability under the influence of abiotic and biotic stressors, assessed through quantitative indices and laboratory methods.
In the reference 336 varieties crop Bread wheat, where this is mentioned in the description.
Tolerance in soft wheat is defined as a quantitative trait evaluated by comparing yield or growth performance under stress and non-stress conditions. Key assessment methods include the calculation of STI, TOL, YSI, and SSI indices, where, for instance, a YSI value ≥ 1 serves as an indicator of high tolerance to moisture deficit. At early ontogenetic stages, cultivar tolerance to edaphic factors, such as soil acidity, is measured using the rolled-towel germination method by assessing the inhibition of root and shoot growth in seedlings.
Cultivars with high tolerance exhibit minimal differences in productivity between control and stress treatments, which ensures yield stability in high-risk farming zones. In modern breeding, DNA markers are used to select such genotypes, in particular markers associated with the TaMYB2 gene for evaluating drought resistance. The tolerance level of a specific cultivar is a determining factor when selecting cultivation strategies, including the determination of seeding density and agrochemical application schemes.
