Researches on the detection of virus diseases of sugar beet in Ankara

Diseased leaf samples were collected from sugar beet fields of Ankara region in 1992. During the surveys, 94 specimens with virus like symptoms were taken from 150 sugar beet fields located in 14 towns and 1 location of Ankara. They were mechanically inoculated to indicator test plants and diagnosed according to the symptoms produced, serological test results and electron microscopy. The specimens suspected as Rhizomania infection were applied to Indirect ELISA test against Beet necrotic yellow vein virus (BNYVV) IgG. According to the results of mechanical inoculation and serological text results, 41 specimens were identified as beet mosaic virus (BMV) and 5 specimens as beet yellows virus (BYV). Rhizomania was not existing in the research area. No results was obtained with the other specimens in the tests, so they were identified as physical disorders or non-mechanical insect transmitted virus infections of sugar beet.
