Abstract
|
|
|
|
Rehimannia glutinose is one of the most important medicinal crops in Korea. However, various plant pathogens including Fusarium sp. cause great damages and cause enormous economic losses. Therefore, this study was conducted to select Fusarium resistant plants by using mutagen-treated Rehmannia glutinosa. The plant material used was a native accession of Rehmannia glutinosa. As a result, among the Rehumannia glutinasa treated with various concentration of EMS, R. glutinosa treated with 0.03M EMS showed higher resistance against infection of F. oxysporum in pot tests, and Rehumannia glutinosa plants treated with 0.12M EMS showed higher resistance against of F. oxysporum in field tests.
