The genus Lycium L. has about 96 species distributed in the temperate and subtropical
zones of both hemispheres. Fruits of about 32 of them are used in food in particular in Chinese
traditional medicine. Recent studies confirm the healing properties of these berries. They are
also rich in carotenoids, vitamin C, specific polysaccharides, betaine, quercetin, and selenium.
Fruits of L. barbarum L. and L. chinense Mill. known as goji, sometimes happen anthocyanin-
rich black goji – L. ruthenicum Murr. In Ukraine, species of this genus have not been
sufficiently studied. In 2015, we began to create a collection and explore the goji in M.M.
Gryshko National Botanical Garden of NAS of Ukraine (Kyiv).
The purpose of the study was to describe the gene pool of plants of the genus Lycium.
The results obtained will help to investigate the biology, ecology of species and evaluate the
prospects of cultivating goji culture in Ukraine.
The objects that have been studied are species of the genus Lycium of a collection of
plants growing in M.M. Gryshko National Botanical Garden (NBG) from seeds, cuttings or
seedlings obtained from China, France, Slovak Republic and other Botanical Gardens of
Ukraine and gardeners. Four species were investigated in an experimental study 2016–2019,
including 10 cultivars and 6 varieties. The biometric parameters of plants were determined:
plant habitus and their annual growth, parameters of vegetative and generative organs, the
passage of phenological phases. The study used one plant per genotype.
The collection includes three East Asian species: L. barbarum and 2 genotypes, L.
chinense and 3 genotypes and 5 cultivars (Big Lifeberry, Sweet Lifeberry, Q1, Delikat, Amber
Sweet), L. truncatum Wang. and 5 cultivars (N1 Lifeberry, New Big, Princess Tao, Korean Big,
Super Sweet). And also one species has a Mediterranean origin – L. europaeum L. All plants
bloom, bind fruits and form viable seeds except L. europaeum. The beginning of vegetation in
all species occurs in the last decade of March to the first decade of April. L. barbarum the first
begins to bloom from late April, mass flowering in all species lasts from June to early
September. Fruits reach a month after flowering. L. barbarum and L. truncatum it bears fruit
from late June to early October, L. chinense from August to October. Variety L. chinense LC02
reach the fruits in October at the latest.
The morphological features of the cultivars N1 Lifeberry, New Big, Princess Tao, Korean
Big, Super Sweet were found to originate from L. truncatum. The Amber Sweet cultivar has the
characteristics of L. chinense and is not L. barbarum as claimed by the originator. Collection of
Lycium spp. in NBG is the basis for the study of representatives of species and their varieties,
selection of promising genotypes and cultivation in Ukraine.
