영문 초록

Bakanae disease, also known as the foolish seedling disease, caused by Gibberella fujikuroi, is a serious issue in Korea. Since2007, there has been a rapid increase in the occurrence of bakanae disease; this has caused severe yield loss to rice farmers every year. The most reliable and economical solution for managing bakanae disease is to cultivate resistant varieties; however, there are only a fewrice varieties in Korea that can withstand this disease. Therefore, this study aimed to evaluate the resistance of 61 major rice varieties whichaccount for 89% of the total rice cultivation area. Only six varieties showed intermediate or higher resistance to bakanae disease; this includedAnpyeong and Samkwang. The genetic inconsistency between the bioassay results and the allele types of 12 molecular markers (associatedwith four QTLs) ranged from 4.7% to 48.7%. Therefore, more accurate markers, such as gene-based markers, are essential for monitoringgeneral breeding programs or gene pyramiding.
