‘Yuryeo’: A Rapeseed with High Oleic Acid, Resistant to Sclerotinia Stem Rot and Lodging

‘Yuryeo’ is a rapeseed cultivar suitable for rapeseed oil production which was developed by the Bioenergy Crop Research Institute, NICS, RDA, in 2018. ‘Yuryeo,’ characterized by its high oleic acid content and resistance to sclerotinia stem rot and lodging, was developed through gamma-ray irradiation of ‘Hallayuchae’ seeds followed by pedigree breeding. Regional yield trials for ‘Yuryeo’ were conducted in three regions from 2016 to 2019. As a result, the flowering period of ‘Yuryeo’ was observed to be two days later than that of ‘Hallayuchae,’ but both had a similar maturation period. In terms of yield, there was no significant difference between ‘Yuryeo’ and ‘Hallayuchae,’ but ‘Yuryeo’ showed higher resistance to sclerotinia stem rot and lodge. Notably, the oleic acid in ‘Yuryeo’ was 74.2%, marking a 10% increase over ‘Hallayuchae.’ With its enriched oleic acid content and reliable cultivation characteristics, ‘Yuryeo’ can enhance both rapeseed cultivation and the rapeseed oil industry (Registration No. 8753).
