While rehmannia (Rehmannia glutinosa Libosch) was identified as a host of at least five viruses, including Rehmannia mosaic virus (ReMV), Youcai mosaic virus (YoMV), Broad bean wilt virus 2 (BBWV2), Plantago asiatica mosaic virus (PlAMV), and Rehmannia virus 1 (ReV1), viral incidence surveys have not been performed yet in rehmannia fields in Korea. In this study, we performed field surveys during 2017-2018 to investigate the incidence of 5 major viruses in rehmannia. A total of 145 symptomatic samples were collected from the rehmannia fields in major cultivation areas of Korea. Molecular diagnosis assays showed that all the collected leaf samples were infected with more than two viruses. Particularly, two species of Tobamovirus, ReMV and YoMV, were detected in all the samples. In addition, our analysis showed that the root stocks of 4 rehmannia cultivars were infected with at least two viruses. Since rehmannia is propagated by vegetative propagation, it is highly important to produce virus-free root stocks of rehmannia to control virus diseases in rehmannia.
