The objective of the study was an attempt at the application of multivariate statistical analysis for the determination of variability, dependence and similarity of phenotypic and field-forming properties of grasspea on the basis of a field experiment, and of the geometry of its seeds and their resistance to mechanical loads in laboratory tests. The research material comprised Polish grasspea cultivars and collection materials representing various geographical regions of Central and South Europe. The results obtained indicated a broad range of variation of the features and traits under analysis, with a distinct division and separateness of forms originating from South Europe with relation to those from Central-Eastern Europe. Based on multivariate statistical analysis the similarity between particular lines and cultivars was determined, pertaining to their phenotypic and yield-forming features and to the geometry of their seeds and their resistance to mechanical loads.
