Abstract :
To study the impact of cobalt gamma rays 60 on the morphologic traits and quality of fatty acids of two types of canola, an experiment was carried out in split plot, completely random blocks with four replications in the educational and research farm of IAU in farming season of 1388-9 in Yasooj branch. The two cultivars of Talayeh and Okapi were chosen as the main factors and the six different levels of radiation including 100, 200, 300, 400, and 500 gray were taken as the sub-plot factors. The results showed that all the traits were under the impact of radiation. The highest seed yield was 3985.26 kg/h, the percentage of oil was 48.32, the percentage of linoleic acid was 11.45, the weight of 1000-grain 5.26g, the yield index 31.5, and the plant height was obtained from 100 gray dose. The highest and lowest seed yield 3998.12 and 1545.81 kg/h were taken from the treatment of 100 gray with Okapi cultivar and 500 gray with Talayeh cultivar. The highest percentage of oil was 49.65 gray and Talayeh treatment; and the lowest percentage of oil with 500 gray and Okapi dose were attained. The highest and lowest yield index were 34.7 and 17.7 respectively from 100 gray treatment with Okapi cultivar and 500 gray with the Talayeh type. 200 gray dose with Okapi cultivar the highest 12.7 and 500 gray dose with Talayeh of 7.6 produced the least percentage of linoleic acid
