Немецкий. Epidemiological aspects of soil-borne virus diseases in cereals were investigated. The occurrence of the bymovirus Wheat spindle streak mosaic virus (WSSMV) and the furoviruses Soil-borne wheat mosaic virus (SBWMV) und Soil-borne cereal mosaic virus (SBCMV) was analyzed in different infested soils of cereal growing areas. In Germany the SBCMV and WSSMV are common mainly in rye and triticale growing areas. Mostly these fields are mixed infestations with both viruses. Monoclonal antibodies are developed for specific discrimination of furoviruses. The disease progress was observed with the help of susceptible standard varieties of winter forms of wheat, triticale and rye depending on different sowing times. Virus infection of plant roots occurred 2 months after sowing independent from the sowing time. The virus detection in these cereals differs during the vegetation time. Two pathotypes of SBCMV were detected by the resistance screening of an assortment of resistant wheat cultivars, double haploid (DH) lines and gene bank accessions of wheat in the infested locations Gödnitz (SBCMV-Gö) and Walternienburg (SBCMV-WN).
