Abstract

Water deficiency is the first limiting factor in SOYBEAN production in semi-arid regions. Therefore, increasing SOYBEAN grain YIELD requires the selection of resistant and adapted genotypes to dry or water deficit conditions of Iran. In this investigation, in order to evaluate the drought tolerance of indeterminate SOYBEAN genotypes, an expriment was performed in a Factorial based on completely randomized design with three replications. The expriment factors included 6 genotypes of SOYBEAN and 3 levels of drought STRESS (control, flowering and seed filling stages). Six drought tolerance indices of MP, GMP, TOL, SSI, STI and HARM were assessed on the basis of grain YIELD in STRESS and non-STRESS conditions. STRESS intensity for flowering stage was low (SI=0.291) while high for seed filling stage (SI=0.429). Based on the results of principle components, two first components totally explained 99.9% of variation among data. The first and second components were named drought tolerance and STRESS susceptiblity component respectively. Based on the results of correlation between drought resistance indices and grain YIELD in STRESS and non-STRESS environments, indices of MP, GMP, HARM and STI were recognized as best indices for selection of tolerant genotypes. Based on the BI-PLOT graph, cultivars Williams and Hack in flowering stage and cultivar Williams in seed filling stage were recognized at a tolerant cultivars.
