Abstract: 

In order to evaluate the effect of water deficit stress (limited irrigation) on different traits of bean. Ten bean genotypes were planted in a randomized block design with three replications under non-stress and drought stress conditions (22 traits were measurement) in the Islamic Azad University of Arak. The results of stepwise regression are shown that the length of the longest pod, number of days to filling pod, number of days to Maturity, 100 weight seed and length of tap root under non-stress condition and number of seed on per plant, 100-seed weight and length of tap root under the stress condition had the most effect on the yield in white bean. Factor analysis showed in the normal condition six factors were identified that over 80% of the performance changes are justified and in the Stress conditions there are seven factors were identified that over 84% of the performance changes are justified. Geometric Mean Productivity (GMP), Stress Tolerance Index (STI) and Mean Productivity (MP) were the most suitable indicators for selecting drought resistant genotypes. Based on these indicators KS 41225, KS 41147, KS 41231 in White beans, were found as resistant genotypes.
