Резюме: The studies were conducted in the Experimental field of Institute of Plant Genetic Resources “K. Malkov”, Sadovo during the period 2006 – 2009. In the investigation were included sixteen cultivars of common winter wheat. The aim of the study was to found correlations between the main structural elements of yield in common winter wheat varieties on the basis of statistical and mathematical processing of the experimental data. It was establishing that in the period of studies the traits: spike length, seeds per spike and grain mass/plant was the most relative variability. PC-analysis was applied to group accessions according to similarity on the basis of nine traits in two components in the factor plane.
