Identifying the corn hybrids for enhanced drought tolerance requires an understanding of the morphological and physiological mechanisms and as well as genetic control of the relevant traits at different plant developmental stages (Bruce et al.
However, further studies are proposed to understand the molecular mechanisms responsible for improving drought tolerance in camelina.
The main objectives of present study therefore were: (i) to determine the mean performance of wheat genotypes for water stress tolerance, (ii) to identify drought tolerance indicators based on morpho-physiological traits and (iii) to determine correlations between various morpho-physiological traits under terminal water stress.
The role of plant breeding for drought tolerance in grapevines then becomes a search for variability of these same traits within Vitis species, and combining multiple, favorable characteristics within the same plant to make a difference.
The knowledge gained could lead eventually to the ability to control the mechanisms of drought tolerance and the development of improved varieties of sorghum and other crops.
Top-rated plants consistently displayed good vigor and robust habits, superior ornamental qualities, disease resistance, heat and drought tolerance, and winter hardiness/survivability throughout the evaluation period.
