The research was carried out in the field at the Central experimental base of the «Federal Williams Research Center» The object of research were 32 samples of bluegrass. Samples are sown according to the scheme of a standard collection nursery. All studies and observations were carried out on the herbage of the 4th year of life. Statistical processing of the research results revealed the average level of variation of signs. Several reliable correlation dependences have been revealed, which can be used as indirect signs in the evaluation and selection of promising breeding material. Multivariate analysis showed that in the bluegrass sample, there are 4 clusters (genetically heterogeneous groups), which can be used for selection on the combinational ability and consolidation of selection — valuable traits and properties. Samples of Kentucky (USA) and Balin (Germany) had the maximum superiority (distance), when paired comparison of Euclidean distances. The use of these samples with a high probability promises to obtain perspective breeding material.
