In 2010, the Central Institute for Supervising and Testing in Agriculture registered 13 new varieties (there had been almost 60 before) of sugar beet into the National Variety Book (7 varieties with Rhizomania tolerance, 5 with tolerance to Nematodes, and one with Rhizoctonia tolerance). Three varieties were registered after three years of testing, the other ten varieties after only two years. In 2009, 69 varieties entered the testing for registration, out of which 43 into the first year. The number of varieties with a special tolerance to Nematodes increased. The experiments are run in two systems of growing: with and without fungicide treatment. The registration of the varieties is based on the results achieved (according to the overall Index indicator).
