Classification based on the plasticity of the response to drought stressors under field conditions (Relative Water Content and Dry Mass), and at 46o C temperature under laboratory conditions (Cell Membrane Stability Index) showed a distribution of wheat genotypes into 2 clusters. The genotypes Mirg./Od.162/M79 and M5/Mirg./Od.162, set at the smallest Euclidean distance 4.3 with the highest Mean values (72.5 and 72.8) were categorized into the cluster with the most advanced tolerance and can be used in improving the genetic gain for drought tolerance.roTriticum aestivum L.relative water contentdry masscell membrane stabilityArticlehttps://doi.org/10.53040/gppb8.2024.32
