摘要：In order to investigation of water deficit on drought tolerance indices of 27 sesame genotypes, a factorial experiment based on randomized complete block design was carried out in Moghan region in 2006 cropping year with three replications. Factors were: 27 sesame genotype (Karaj 1, Yekta, Oltan, Moghan 17, Naz takshakheh, Naz chandshakheh, Borazjan 2, Borazjan 5, Darab 14, Varamin 37, Varamin 237, Varamin 2822, Zoodrass IS, Hendi, Chini, Yellow white, 5089, Panama, DO-1, TF-3, TKG-21, J -1, RT-54, Hendi 9, Hendi 12, Hendi 14 and Jiroft) and irrigation (complete irrigation and irrigation until beginning of flowering). Results showed that Varamin 2822 genotype and Hendi 12 genotype in stress conditions had the highest yield stability about tolerance (TOL) and Mean Productivity (MP) indices, respectively. Regarding to Geometric Mean Productivity (GMP), Karaj 1, Oltan and Naz takshakheh were at highest level. Based on Stress Susceptibility Index (SSI), Varamin 237, Naz takshakheh, Naz chandshakheh, Oltan, Hendi 12, J-1, Panama genotypes and Jiroft line, were among mid-resistant and Zoodrass IS genotype was as sensitive one. Based on Stress Tolerance Index (STI), Varamin 2822, arranged as midÃ¢â,¬âOresistant genotype. So, Karaj 1, Naz takshakheh, Varamin 237 and Varamin 2822 had highest rates (about mentioned indices) and are suitable for cropping under drought stress conditions.
