Abstract— Biofuels are the main alternative for changing the world’s energy matrix, which is now centralized in fossil fuels. The characterization of alternative sources of biomass, mainly regionally, shapes database for decision making.For this purpose, a factorial experiment was carried out with three canola cultivars (Hyola 43, 61 and 571), seeded in four times (April 4th, April 16th, May 2nd and May 14th).As biomass characterization, grain yield, oil content and yield, specific mass, oxidative stability, acidity and lipid profile were determined. There was significant difference for the hybrids in the variables oil content, induction time and in the stearic, linoleic and linolenic contents. The highlight was the hybrid Hyola 43.There was significant difference for the periods in the grain yield, oil content, oil yield, and induction time and in the palmitic, stearic, oleic and linoleic contents. Considering values of dependent, quantitative and qualitative variables, the best seeding season of canola would be between the second fortnight of April and the first week of May.
Keywords— Biodiesel, vegetable oils, fatty acid.
