Tolerance — Durum Wheat

Triticum durum Desf.

Durum wheat tolerance is the ability of a genotype to maintain productivity under abiotic stress conditions such as drought, salinity, and high temperatures.

In the reference 52 varieties crop Durum wheat, where this is mentioned in the description.

To assess tolerance, stress resistance indices such as STI, TOL, MP, GMP, SSI, YI, and YSI are used, which are calculated by comparing the yield and physiological parameters of varieties under stress and favorable conditions. High values of STI, MP, and GMP indicate varieties that demonstrate stable productivity regardless of external factor impacts.

Evaluation methods include field trials with irrigation control, laboratory seedling screening in osmotic solutions, and analysis of physiological indicators such as relative water content in leaves, enzyme activity, and the K+/Na+ ion ratio in tissues. The selection of tolerant varieties helps to minimize the risks of yield loss and maintain high grain quality indicators, including vitreousness and protein content, in regions with adverse climatic conditions.
