Abstract :Sugar beet bait plants grown in soil samples collected in central and northern parts of Turkey were previously found to be infected with Beet necrotic yellow vein virus insert ignore into journalissuearticles values(BNYVV); and Beet soilborne virus insert ignore into journalissuearticles values(BSBV); through enzyme-linked immunosorbent assay insert ignore into journalissuearticles values(ELISA);, and with Polymyxa betae using direct coloration method of bait plant root tissues. The effects of BNYVV, BSBV and P. betae, alone and in combination on the growth of sugar beet seedlings were investigated by considering root weight and the mean ELISA values. The result from the statistical analysis showed that total fresh root weight was negatively correlated with BNYVV, BSBV and BNYVV+BSBV infections, but not with aviruliferous P. betae infection. Additionally, the most common symptom after six weeks growing periods was chlorosis for single BNYVV insert ignore into journalissuearticles values(46%);, BSBV insert ignore into journalissuearticles values(28.1%); and double BNYVV and BSBV insert ignore into journalissuearticles values(58.5%); infections. Also, the number of plants with no visible symptoms in single BSBV infections insert ignore into journalissuearticles values(60.3%); was higher than that obtained in single BNYVV infections insert ignore into journalissuearticles values(39.5%);. Most of plants insert ignore into journalissuearticles values(65.3%); infected with aviruliferous P. betae populations had no visible symptom, however, 24.7% of the plants showed chlorosis. This study indicated that various populations of both sugar beet viruses and P. betae could be present in the region, and BNYVV seems to provoke chlorosis in both single and double infections
