The Latest Domestic and Foreign Trend on the Fatty Acid Composition Improvement in Rapeseed Oil and a New Proposal for Korean Rape Breeding

Recent directions in rape breeding have been focused on quality improvement breeding of oil and cake. The goals to increase the composition of good fatty acids in rape oil and to genetically control and/or reduce the Formation of noxious fatty acids. The increase of good quality fatty acids in rape oil and rape cake would sllow increased utilization of rape as a domestic animal feed by reducing the harmful glucosinolate of the cake. Currently Korea is breeding for improved fatty acids in rape oil. High-yielding O-erucic acid strains have been succesfully selected at the Mokpo Branch Station of the Crop Experiment Station. Basic Studies on shortening rape’s life cycle by 70 days to allow 4-5 generations per year are under way. Other projects include the use of male sterility to exploit heterosis and to increase the efficiency of quality improvement breeding and the breeding of high-yielding good fatty acids varieties adapted to the southern part of Korea.
