The genus Lonicera L. (Caprifoliaceae) includes about 200 species, growing in temperate
Holarctic. Lonicera caerulea L. s.l. is widely cultivated nowadays as an edible plant. This is very
polymorphic species and is regarded by some authors as a complex of microspecies or
geographical races, including L. altaica Pall., L. pallasii Ledeb., L. ×subarctica Pojark., L. edulis
Turcz. ex Freyn, L. stenantha Pojark., L. buschiorum Pojark., L. baltica Pojark., L. turczaninowii
Pojark., L. kamtschatica (Sevast.) Pojark. and L. iliensis Pojark.
Lonicera caerulea is valued for ultra-early fruit ripening, as well as a high content of
biologically active compounds with antioxidant, immunomodulating, antibacterial, antiviral,
antifungal, antiallergic properties. It is used in medicine, cosmetic and food industry.
The aim of this study was to determine the variability of morphometric characters of
fruits of L. caerulea. Reaction norm of fruit’s characters is very high, this was the base for the
creation of many cultivars in the Russian Federation. The results obtained in M.M. Gryshko
National Botanical Garden of NAS of Ukraine (NBG) will help us to select the most promising
samples for further breeding work. Plants of L. caerulea of seed’s origin growing in Forest-
Steppe of Ukraine in NBG were the objects of the research. There were 26 genotypes tested in
an experimental study in 2017–2018. Pomological characteristics were made on a total of 30
fruits per genotypes. The following measurements were taken: fruit weight, in g, fruit length,
in mm, fruit diameter, in mm.
Our collection includes more than 40 genotypes of seed’s origin from European Russia,
Kuril, and Canada. The differences in weight, shape, size, the color of fruits and the degree of
the wax coating were noted. Mature fruits are dark blue, nearly black in color. The shape of
the fruits may be ovate, narrowly oblong, broadly oblong, obovate, campanulate; the shape of
the calyx end is rounded, truncate, acute; The morphometric parameters were following: fruit
weight from 0.73 to 1.60 g, fruit length from 16.42 to 27.29 mm, fruit diameter from 7.77 to
12.34 mm. The shape indexes of fruits varied from 1.51 to 3.52. The analysis of the coefficient
of variation showed the difference of variability of morphological signs between L. caerulea
samples. Data showed that the most variability of important selection signs is the fruit weight
from 14.09 to 34.50 %. The results indicated a high positive correlation between fruit weight
and fruit diameter (r = 0.847).
The outcome of the research point to the fact that the Ukrainian gene pool of L. caerulea
is a rich source of genetic diversity and might be used in selection for creating new genotypes
and cultivars. The complexes study of phytochemical characters of the available Ukrainian
genotypes was started by Ukrainian, Slovak and Russian scientists in Slovak Agricultural
University in Nitra (Institute of Biodiversity Conservation and Biosafety). The comparison of
phytochemical characters between Russian ancestors and its seed’s generation will be made
next year.

Keywords: Lonicera caerulea, fruits, morphometric parameters.
