Tests carried out to determine the saponin contents in lucerne have shown that there is a considerable genotypic variability. Genotypes having high, medium or low saponin contents when evaluating the whole plants from the first cut had similar contents in further 2 cuts when evaluating leaves and stems separately. No significant difference was found when evaluating whole plants, and their individual parts separately. Insignificantly higher variability was found in repeated tests with whole plants as compared to testing of leaves and stems. Insignificantly lower variability was found in tests of leaves compared to stems. Higher saponin contents were found in the buttonizing phase than during flowering. In the 2nd cut in the flowering phase higher saponin contents were found than in the 3rd cut. The saponin content in leaves was approximately double of that found in stems.
