Abstract

To evaluate the DROUGHT TOLERANCE indices in SUNFLOWER cultivars an experiment was conducted in split plot design based on randomized complete block design with three replications at two levels (Drought stress and non-stress condition) for 8 cultivars of SUNFLOWER in farm research of Islamic Azad University, Tabriz branch, during 2008 planting season. Based on yield under non stress condition (YP) and stress (YS), quantitative indices of DROUGHT TOLERANCE, such as: tolerance index (TOL), geometric mean productivity (GMP), harmonic mean (MH), stress susceptibility index (SSI ) and stress tolerance index (STI) were calculated. In both conditions the highest grain yield and the highest GMP, MH and STI were for “Ghalami” cultivar. Simple Pearson correlation coefficient between above indices and average yield of seed and oil in stress and non DROUGHT STRESS conditions showed, TOL index with oil yield and STI, GMP indices with seed yield had positive significant correlation in both stress and non stress conditions. Therefore, STI, GMP were sujested according to seed yield and TOL was recommended in the basis of oil yield for tolerant cultivars selection respectively. Based on the above superior indicators, Pen and Haysan 33 cultivars identified as the most tolerant cultivars in the basis of seed and oil yield characters alternatively.
