摘要

Oil of rapeseed has been used mainly edible oil from old times. Also it is used by raw materal of biodiesel for substitution of fossil fuel at present. Breeding for improvement of fatty acid composition in rapeseed has been emphasized for high quality rapeseed breeding in Korea. Most of the Asian varieties have high oil content, but lower oleic and higher erucic acid content than the European varieties. The variation in the oleic and erucic acid content in the European varieties were larger than in the varieties from Asian countries. The possibilities of isolating of a plant free from erucic acids on Asian varieties and lines were detected in study. Therefore, Canadian variety of summer rapeseed with high oleic acid and zero erucic acid was reciprocally crossed with high erucic acid varieties to introduce two recessive zero erucic acid genes to Asian varieties. It was selected 20 lines containing oleic acid over 65%. The erucic acid showed the negative correlation with oleic and linoleic acid.
