Abstract
Examined soybean collection was obtained from the National Centre of Plant Genetic Resources of the Plant Breeding and Acclimatization Institute at Radzików. In this paper statistical methods such as correlation analysis and factor analysis were used to detect the relationships between 13 tested traits and for grouping closely related traits in classes and in groups of early and late maturing accessions of soybean collection. There was very close relationship between productivity traits (seed weight, seed number and pod number per plant). Those relationships were confirmed by factor analysis. Calculated principal components connected with mentioned above productivity traits explained in the highest degree total variability of examined traits in all classes of soybean collection accessions.
