چکیده

in order to evaluate drought tolerance of chickpea genotypes and identifying the best indices of drought tolerance, the 20 genotypes desi chickpea plus two improved cultivars (kaka and piroz) were tested using a randomized complete block design under two irrigated (non stress) and (stress) conditions. quantitive drought tolerance and susceptibility indices such as stress tolerance index (sti), stress susceptibility index (ssi), mean productivity (mp), harmonic mean (hm), tolerance index (tol) and geometric mean productivity (gmp) based on yield in stress and non stress conditions were calculated. there were significant variations among the genotypes in their reaction to drought tolerance. there were positive and highly significant correlations among gmp and sti with yield in stress and non stress conditions. also, there were positive and hight significant correlations for tol and ssi with yield in stress. the correlation between seed yield, in stressed and non-stress conditions, and drought tolerance indices indicated that sti and gmp were the more suitable indices for screening of desi chickpea genotypes for drought tolerance. comparison of three dimension plot and bi-plot showed that in stress condition, genotypeskc-218625,kc-217667 andkc-218553 were more tolerate genotypes.

Evaluation of Drought Tolerance in Barley Genotypes (Hordeum vulgare L.) using Drought Tolerance Indices

Extended Abstract Introduction and Objective: Drought stress is one of the most important factors in reducing yield and barley production in rainfed arid regions, and counteracting or reducing the effect of stresses as a useful solution to increase barley yield. Therefore, improvement of stress-tolerant and suitable barley cultivars for arid and semi-arid regions is essential. Material and Me...

Evaluation of grain yield and repeatability of drought tolerance indices for screening chickpea (Cicer aritinum L.) genotypes under rainfed conditions

In order to identify drought tolerant chickpea genotypes, an experiment was conducted in the west of Iran, during 2007-2009 cropping seasons. Several selection indices were used to illustrate genotypic differences in response to drought stress. The results of combined analysis of variance showed that year, genotype, stress conditions and their interaction effects were highly significant. Correl...

Using Drought Tolerance Indices in Evaluation of Some Wheat, Triticale and Tritipyrum Genotypes

To evaluate drought tolerance in bread wheat, tritipyrum and triticale genotypes, 27 different genotypes were grown as a randomized complete block design under two irrigation regimes (control and drought) in two locations (Isfahan and Shiraz) during two growing seasons (2016 and 2017). Based on grain yield, several indices including stress tolerance index (STI), tolerance index (TOL), susceptib...

Identification of Drought Tolerant Oilseed Rape Genotypes using Multivariate Analysis

Extended Abstract Introduction and Objective: Drought stress as one of the most important abiotic stress is the main limiting factor of oilseed rape cultivation in arid and semi-arid climates. Therefore, the identification of drought tolerant genotypes is the essential programs in these regions. One of the appropriate methods to identify drought tolerant genotypes is the use of stress toleranc...

Evaluation of Drought Tolerance in Rapeseed (Brassica napus L.) Cultivars Using Drought Tolerance Indices

Drought is the most significant constraint for crop production in arid and semi-arid regions. In order to assess drought tolerance in fifteen rapeseed (Brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of College of Agriculture, Shiraz University, Shiraz, Iran during 2009-2010 growing season. The cultivars were...
