The soybean (Glycine max l. merr) is one of oil seed plants from leguminous family. In this study, the effect of gamma radiation on chlorophyll, soluble and insoluble carbohydrate and composition oil seeds were investigated in soybean. Soybean variety J.K was irradiated with 0,100,200 and 300 gamma ray. The treatment and control seeds planed in with four replicates. The highest amount of total chlorophyll content was obtained in control plants. The highest amount of soluble carbohydrate was obtained in 200 gamma ray treatments. The contents of carbohydrates   in the leaves tend to increase with increasing gamma ray doses. The elevated levels of the total soluble and insoluble carbohydrates in leaf are considered to be playing an important role in the osmotic adjustment. The results showed that the highest amount of total protein content was obtained in control plants. The contents of protein in the leaves tended to decrease with increasing gamma ray doses. The oil soybean seeds were extracted and analyzed for their chemical and physical properties such as acid value, percentage free fatty acids (% FFA), iodine value, and refractive index.
