Abstract :

      For evaluation of gamma radiation at different intensities on the qualitative and quantitative traits in sesame, the experiment  was conducted in a factorial with  completely randomized block design  using four replication in Firouzabad. Before planting, 15 grams of sesame seeds for each plot was exposured with gamma rays at  100, 200, 250, 300 and 350 Gary in the Karaj Nuclear Agency. Properties that were studied include: height. The number of lateral branches, number of capsules, during the flowering period, yield per plant, grain weight, percentage of protein and oil. According to properties were measured and comparisons,treatment of  200 Gary showed positive effects. Maximum of yield (1669 kg/ha), plant high (108cm), grain weight (3.27 gr) was related to 200gry treatment and Maximum of percentage of protein (56) and number of capsules (182 per plant) was related to 150 gry treatment..higher doses ,especially 350 Gary, had negative effect on characteristics of the study.Yield has negative correlation with during the flowering period but it has positive correlation with another treats and highest correlation was between yield and grain weight.
