Genotypic differences of oil content, oil composition and seed production were studied in six line varieties of Brassica napus L (ES Astrid, Atlantic, Californium, Labrador, Manitoba and Oponent) which represented 3 major production region of Slovakia. For experiment the standard agrotechnical procedure was used. Seed were sown on August 27, 2007 and harvest has been done on July 11, 2008. It was found that the lowest seed production but also low values of lipids and oil content has var. Californium. This variety together with var. Oponent and Labrador had higher ratio of low molecular components in the oil. For these varietes low values of iodine number as well as phosphorus content were estimated. Content of the most important of fatty acids - oleic acid ranged from 60.02% (Labrador) to 65.80% (Atlantic). Seeds of all studied rapeseed varieties had low content of linolenic acid (8.34 - 9.59) which is important for oxidation stability of FAME. From this aspect is var. Atlanitic the most suitable for practical application. The content of eruic acid in the oil of tested varieties ranged from 0,01 to 0,05%.
