Eucalyptus embrace over 700 species although the core of genotypes used in commercial plantations has as little as nine species and their hybrids. Plantations are expected to fulfill the demand for harvesting timber and other commercial uses, sometimes, notwithstanding with plant survival resilience as not all tolerance strategies will fit industry interests. The diversity of eucalyptus strategies in response to drought join its variability in size, from shrubs to high trees, and adaptations to climates, from xeric to lowlands. There are several reports on eucalypts submitted to abiotic stress that contribute to the understanding of the sustained growth, although only a few recommend genotypes to be cultivated under these conditions. Different sets of structural, nutritional, physiological and other features, subsidize plant adaptability and growth, in a kind of functional homeostasis. Growth and adaptability traits are considered as markers for water stress tolerance or, at least, as a baseline for comparison. Some of these traits are found in responses to abiotic stresses other than water deficit and may be inherent or evolved for particular species. These processes may be the result from acclimatization or speciation/environmental selection what support selection for tolerance be performed under water deficit conditions. Our early experience indicates that joint analysis of selected, high accuracy and suitable heritability biomarkers support the identification of commercial eucalypt genotypes to be cultured under water scarcity conditions.  aAbiotic stress  aEucalyptus  aStress tolerance  aWater stress  aÁgua  aEucalipto  aGenótipo1 aRESENDE, M.
