In this work the investigations ot technical properties of 16 rapeseed samples cultivated in 2004, including 3 of them for other location, were carried out. The technological properties of seed from new varieties and hybrids were determined as well as some properties of corresponding oils. The results of the determination of impurities content, mass of 1000 seeds, volume mass and oil content verified the good rapessed gualiy. Water content in seed samples was over critical 7%, and oil content was from 33,41% to 41,52%, according to variety and location. In rapeseed oil, the fatty acid composition, specific absorptions in UV area at 232 nm and 270 nm, as well as colour index and chlorophyl content was determined. Erucic acid was absent in all investigated oils. The most represented fatty acid was oleic acid, followed by two polyunsaturated acids (linoleic and linolenic), what is the basis for high nutritive quality of rapeseed oils. Content differences of all fatty acids, between varieties and two locations are statistical important. Some values for oleic and palmitic acid were over, and for linoleic and linolenic were under those registrated by Regulatory, and must be taken care of during writing new legal regulation. Colour index of investigated oils was low, like total chlorophyll content. Spectrofotometric analysis in UV area showed larger amount of conugated diens and triens than that in olive oil.
