Abstract


In order to evaluation of physiological characteristics, yield and yield components of winter-sown chickpea genotypes under rain-fedcondition a field experiment was conducted at Agriculture and Natural Resources Research Station of Ardabil during the 2010-2011growing season. The experiment was carried out in a randomized complete block design with 15 chickpea genotypes replicated threetimes. Water content, relative dry weight, cell membrane stability (CMS), injury cell index (ICI), excised leaf weight loss and yieldcomponent were investigated. The results of variance analysis showed that chickpea genotypes had significantly differences in all of
measured characteristics. The assessment of plantwater relations revealed that the maximum RWC belonged to S99326 × SEL99TH15042 genotype. The Flip98-138C Sel99TER85074 SEL99TH15039 genotype had highest CMS. The highest seed yieldper plant, pods per plant and 100-seed weight were recorded for Flip97-118C, CA9783007 Sel99TER85534 and (ILC4291 Flip98-129 C) S98008 genotypes. These genotypes were expected to provide higher yields after severe drought than those genotypes with high
susceptibility.
