Thirty-four genotypes of Lonicera caerulea species originated from germplasm collection of the Forest-Steppe of Ukraine in M.M. Gryshko National Botanical Garden of NAS of Ukraine (NBG) (Kyiv, Ukraine) and were characterized by using the morphometric traits and iridoids content. Differences between the genotypes were significant in all observed parameters. The fruits of L. caerulea collection varied in evaluated morphometric parameters as follows: fruit weight 0.70–1.54 g, length 15.33–26.52 mm, diameter 7.12–13.10 mm. The shape indexes of fruits varied from 1.42 to 3.65. Our results showed that the content of iridoids ranged from 97 to 314 mg.100 g</span><sup>-1</sup><span style="font-size: 0.875rem;"> of fresh <em>L. caerulea</em> fruits. Interestingly, <em>L. caerulea</em> berries taste differs between the varieties, those with bitter or sour-bitter taste are distinguished by the highest content of iridoids (225–314 mg.100 g<sup>-1</sup>), while berries without bitter taste were characterized by significantly lower contents. Thus, honeysuckle berries should be selected preferentially regarding their bitterness, due to the anti-inflammatory and antioxidative properties of iridoids.</span></p> ER -
