Determination of duplicates of accessions in a germplasm collection of flax/linseed by means of digital image analysis

► Image analysis of petals precisely discriminate varieties. ► 9 morphometric features concerned also the same passport data. ► We use image analysis and hierarchical cluster methods for validation. ► The method determines the distance in clusters and varietal identification. ► Image analysis resulted in duplicates of accessions in a group of flax/linseed collection.
