Varietal microtrials with fifteen sugar beet cultivars characterized with different tolerance to Cercospora beticola, rhizomania and Rhizoctonia solani were set according to standard methods at two localities (Sombor and Stara Pazova) in four replicates. The obtained results showed that root yield varied from 77,08 t/ha for cultivar No. 14 (Sombor site) to 114,49 t/ha for cultivar No. 7 (Stara Pazova site). High variability in the root sugar content was observed that ranged from 14,32 % for cultivar No. 8 (Stara Pazova) to 20,10 % for cultivar No. 3 (Sombor). Granulated sugar content, as the most important quality parameter, reached the best figure in the cultivar with the highest tolerance (17,096 t/ha) whereas it was the lowest in the case of the least tolerant cultivar (10,465 t/ha). The difference in this parameter can be considered as very high (6,631 t/ha) in favour of highly tolerant cultivar.
