| Abstract: | In comparative experiments for detecting apple chlorotic leaf spot virus (ApCLSV) in apple cultivars and wild apple varieties using graft indexing the procedure of applying the woody indicator clone Malus pumila MILL. Comparing R 12740 7A and the DAS‐ELISA technique, the reliability of the ELISA in ApCLSV detection in fruit‐bearing cultivars proved to be slightly better than that of R 12740 7A. In certain taxa of wild apple varieties, however, the reliability of the graft indexing procedure in detecting ApCLSV proved to be much better than that of ELISA. The investigation was carried out with 864 trees belonging to 16 apple cultivars and 24 wild apple varieties, respectively. |
