Abstract
Bacterial soft rot by Erwinia carotovora subsp. carotovora is one of the diseases causing the biggest damages in Chinese cabbage cultivation. This study was conducted to evaluate disease resistance of Chinese cabbage cultivars and breeding lines to E. carotovora subsp. carotovora by new inoculation method, mineral oil inoculation method, inoculating 10 ml of the mixture (4:1, v/v) of bacterial suspension and mineral oil on the central bases of Chinease cabbage seedling. Total 43 Chinese cabbage cultivars and lines obtained from 3 domestic seed companies and universities were screened for disease resistance using the above mentioned inoculation method. This screening test showed that Chinese cabbage C3-26, C3-28, C3-29 and C29-51-51-53 lines were resistant, Gangta, Gumchonyealgali, Mini, DB50, Jibu, Pyungchng, Sanchon and Yellow King No. 2 cultivars were susceptible, and the others were moderate resistant.
Key Words: Chinese cabbage, Erwinia carotovora subsp. carotovora, mineral oil inoculation method, disease resistance
