It is characterized by high and stabile yield potential andgood biomass quality. The aim of this study was to determine genetic and phenotypic correlation coefficients of seven most important traits of two synthetic cultivars (Kruševački 21 and Pradel). Individual plants for hybridization, in order to obtain progeny by the method of Comstock and Robinson, were selected completely randomly. In order to examine the obtained progeny, the study was performed in an experimental field of the Institute for Forage Crops, in two replications. The experiment was set up according to the Nested Design I, with sets within the replications. In Kruševački 21, 60 full-sib progeny were studied in two sets, while in the Pradel a total of 39 full-sib progeny were studied. Within each full-sib progeny, 60 plants were analyzed. Statistically and high statistically relation was obtained between some traits and presented as genetic (rg) and phenotypic (rf) correlation coefficients. In cultivar K-21 very high statistically significant genetic correlation coefficients were determined between heading date and leaf length (rg=0.873**), plant height and number of generative tillers per plant (rg=0.893**) and dry matter yield in the first cut and annual dry matter yield (rg=0.988**). In cultivar Pradel very high statistically significant relationship was obtained between heading date and plant height (rg=0.978**), heading date and number of vegetative tillers per plant (rg=0.926**) and annual dry matter yield with one side, and plant height (rg=0.912**) and dry matter yield in the first cut (rg=0.978**), on the other side.enCC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/meadow fescueNested Design Igenetic correlation coefficientsphenotypic correlation coefficients.conferenceObject
