Drought stress often is a limited factor in world that threatns crop yield. Application of breeding and
selection of tolerant genotypes to abiotic stresses are logical approach for determination of tolerant genotypes
that have a high performance under drought. In order to study quantitative and qualitative traits and their
relationships with grain yield in white bean genotypes under optimum and limited irrigation conditions, 15 white
bean genotypes were studied in (WO experiments using randomized complete block design with three replications
in experimental field. Faculty of Agricultural, The University of Tehran in 2004 cropping season. Combined
analysis of variance showed high genetic variation for most of the traits. Some traits had high genetic variation
under both conditions. Stress Susceptibility Index (SSl), Geometric Mean Productivity (GMP) and Stress
Tolerance Index (STI) had positive correlation with yield under optimum and limited irrigated conditions. Thus
genotypes with greater GMP, STI and lower SSI were identified as the tolerant genotypes. For further
evaluation, biplot was used. Four genotypes including No. 1,2, 3, 5 and 14 were identified as tolerant genotypes
and STI ,GMP, MP indices were determined as suitable indices in screening for drought tolerance.
