Wheat, is the main crop and food for majority of people in the world, due to adaptability in different
environmental climate conditions, it exposes difficulty dry lands. In order to improve the new crops, high
capacity and stability of production is an important issue. Since heritability is low and selection on it cannot
be effectual, nowadays more modified plants are based on physiological characteristics which have
potentiality and higher heritability. To this point, in the department of Dry land Agricultural Research
Institute in the of Kermanshah Sararood in the cultivating year 2012-2013, an experiment with 4 kind of
wheat cultivar (Sardari, Azar-2, Ryzhav and Karim) and 18 advanced lines conducted in a randomized
complete block design with three replications. The trait of relative water content, and loss water leaf was
measured. Clustering cultivars and lines and biplot resulting of analysis showed that cultivar Ryzhav with
line 9 contain highest relative water content and lowest loss water leaf, and drought tolerance and lines 19
and 8 contain the lowest level for both characters and susceptible to drought.
