During 2001-2003, 30 lucerne genotypes of different geographic origin were studied at Rimski Sancevi (Serbia) over seven cuts. The genotypes were broadcast-planted into hills 0.8 x 0.5 m in size in 2001. Ten agronomically and morphologically important traits were studied: yields of green forage and dry matter, plant height, number of shoots (stems) per plant, internode number and length, length and width of the middle leaf blade, proportion of leaves in the yield, and stem diameter. Genetic and phenotypic correlations among the morphological and agronomical traits of the genotypes were calculated. Genetic correlations had higher values than the phenotypic ones. Studying the effects of genetic and environmental factors on yield and yield components is of great importance in lucerne breeding, as is the knowledge of genetic and phenotypic correlations among lucerne traits and their practical application (especially in tandem selection).
