Abstract

In order to investigate of WATER DEFICIT STRESS TOLERANCE INDICES in four SAFFLOWER genotypes (Carthamus tinctorius L.), this experiment was conducted in field research station of Islamic Azad University of Arak, Iran during 2008-2009. The experimental design was split plot based on randomized complete blocks design with four replications. The treatments composed of irrigation levels 100%, 75% and 50% crop water requirement as main plot and four SAFFLOWER genotypes included Esfahan native, Esfahan-14, PI-537598andIL-111 as sub plot. TOLERANCE INDICES including: Mean Productivity (MP), Tolerance Index (TOL), Stress Susceptibility Index (SSI), Stress Tolerance Index (STI), Geometric Mean Productivity (GMP) and Harmonic Mean (Harm) were calculated. The results showed that the highest GRAIN YIELD in optimum, moderate and severe stress condition was obtained from Esfahan native genotype. According to STI, MP, GMP, Harm indices Esfahan native genotype and on the basis of SSI and TOL indices IL-111 genotype in optimum and stress conditions were the higher tolerant to WATER DEFICIT STRESS. STI, MP,GMP, Harm indices were showed correlation positive and significant with GRAIN YIELD in optimum, moderate and severe stress condition. Therefore using STI, MP,GMP, Harm indices can selected genotypes with high yield in optimum and stress condition.
