Abstract

To evaluate and select drought tolerance genotypes in common bean and identify the best indices for drought tolerance, an experiment was conducted at research field University of Tehran, Karaj, Iran, during 2015-2016 growing season. In this study, 102 common bean genotype were evaluated in an augment design under normal irrigated and drought stress (non-irrigated from flowering stage until the end of growing season) conditions. Average values of grain yield and drought tolerance indexes and simple correlation coefficients of indexes with irrigation and dry farm yield showed that indices including MP, GMP and STI were the most suitable criteria for screening bean’ s genotypes. In 3-dimensional graphs, referring to MP, STI, and GMP indexes and grain yield under dry farming and irrigation condition, 100, 63, 47, 88 and 76 genotypes were identified as genotypes with high production and tolerant to intensive drought in A group. Actually, these genotypes had the highest yieldunder both irrigation and dry farming conditions. Cluster analysis based on investigating indices and yield under drought stress and non-stress conditions showed that genotypes was grouped in three clusters and most of drought tolerant genotypes with high yield were grouped in third cluster, while most of sensitive genotypes to drought stress were grouped in the second cluster.
