Abstract

The development of safflower cultivation is very important for Iran to meet the country's demand for edible oil. Although, safflower is a native plant of Iran and has the advantage of good resistance to salt and drought stress, only limited research has been carried out to identify specific crop traits that contribute to this tolerance. This experiment aimed to evaluate the effect of drought stress on seed and oil yields, yield components, oil percentages and some agronomic characteristics of spring safflower genotypes. The experiment was, factorial using complete randomized block design with three replications; normal irrigation and water deficit stress at both the stem elongation and flowering stages using six genotypes. The results revealed that the flowering time was the most sensitive stage to water deficit. Analysis of variance showed high genetic diversity between the genotypes for the studied traits: genotypes 34069, K.H.64.68 and340779 had the highest averages of traits in nor
