In order to study the effect of drought stress on seed yield and some physiological and biochemical characteristics of different genotypes of red bean an experiment was performed in split plot based on randomized complete block design with three replications at the research field of Islamic Azad University, Arak. The main plot factor was irrigation surfaces (normal and stress); irrigation was cut in flowering and pod filling and the sub plot factor was red bean genotypes including Derakhshan, D81083 and Goli. The Analysis of Variance showed that the draught stress significantly affected leaf relative water content, electrical conductivity of the cell membrane, leaf proline content, protein content, concentration of soluble sugars. Goli genotype had the highest relative water content, protein content and D81083 and Derakhshan genotype had the highest proline content and lowest electrical conductivity of the membrane was proline the result of the experiment indicates the stability of the cell membrane. Derakhshan and D81083 genotypes contained highest soluble sugars. D81083 and Goli genotypes showed their superiority in traits under study in this experiment and therefore can be cultivated in areas where there is water shortage.
