![]() ![]() ![]() The range of linoleic acid and α-linolenic in three regions were 57.55 to 63.98% and 7.57 to 22.91%, respectively. The most abundant fatty acid in the samples was linoleic acid, (56.80 to 63.98%), and almost identical in all cultivars and areas studied. It was also determined that Alborz was significantly higher in terms of oil production, 1000-seed weight, and seed and oil yield per hectare compared with the other two regions. Based on the results, the highest seed yield, 1000-seed weight, and oil yield belonged to native populations. The oil content of different varieties varied from 15.46 to 36.63%. Also, the range of 1000- seed weight was 5.20 to 15.28 g. The seed yield was 288.70 to 3182.60 kg ha-1 and oil yield were 0.08 to 0.95 t ha-1 in the studied sites. The mature seeds of cultivated plants were collected and their oils were extracted by Soxhlet apparatus and analyzed by Gas Chromatograph. Seeds of two native populations from Iran (Fars and Yazd provinces) and one foreign variety from France (Fedora17, as an industrial hemp cultivar) with its progenies (Fedora17-2) were cultivated in research fields of three locations (Gilan, Golestan, and Alborz province) in Iran. Given the economic and industrial importance of hemp, the present study was designed in an endeavor to select and compare the best cultivar and region to increase both quantity and quality of hemp oil from Iran. Hemp oil has been widely acknowledged to have a panoply of health benefits, such as cholesterol lowering properties and decreasing high blood pressure, owing to the presence of two essential fatty acids (linoleic acid and α-linolenic). Cannabis sativa L, commonly known as Hemp, shows numerous health and economic benefits with commercial applications such as in seed production, fiber, oil, and pharmaceutical uses. ![]()
