Goji berries are a new promising food and medicine crop. Under the name of the goji, use
the fruits of two species of genus Lycium L.: L. barbarum L. and L. chinense Mill. Goji berries
have a high antioxidant effect, anti-hyperglycemic, anti-cancer, and anti-aging properties, due
to the presence in the fruits high amount of ascorbic acid, specific polysaccharides and
betaine. Under the crope of goji in China, more than 150,000 ha are occupied, they are grown
in Europe and the USA. Berries are consumed in fresh and dried form, juices, wine, preserves
and as the substitute of tea made of leaves. There is a limited amount of data on the biology of
this species in the literature. In Ukraine, it has not been investigated or grown in the industrial
size. 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 determine the variability of some morphological
characteristics of fruits L. chinense. The obtained results will help to select promising
genotypes for further breeding work and to evaluate the prospects of promising using
selected samples.
The objects that have been studied are fruits L. chinense of a collection of plants growing
in M.M. Gryshko National Botanical Garden of NAS of Ukraine from seeds or cuttings obtained
from China, France, Slovak Republik and other botanical gardens of Ukraine. Eight genotypes
were investigated in an experimental study in 2018, including 3 cultivars (Big Lifeberry,
Delikate, Q1) and 4 varieties. Morphometric characteristics are derived from 50 fruits per
genotype. The study used one plant per genotype. The following measurements were made:
the weight of the fruit (g), the length (mm), the diameter (mm), the number of seeds per fruit.
The fruits differed in weight, shape, size, color, and number of seeds. Rugged fruits in
different genotypes acquire orange, red to dark red color. Morphometric indices were as
follows: fruit weight from 0.62 to 0.99 g, fruit length from 8 to 15 mm, fruit diameter from
8.03 to 13.54 mm, seed number in fruit from 16 to 28, fruit form index varied from 0.76 to
2.34. Analysis of the variation coefficient showed differences in the morphological
characteristics between L. chinense samples. The data showed that the most varied is the
number of seeds in the fruit from 8.78 to 38.63 % and the weight of the fruits is 16.32 to
22.92%.
The results show a narrow reaction norm within the introduction population. The two
selected genotypes LC03 and LC04 are characterized by a greater weight of fruits than the
studied varieties. Varieties LC01, LC02, LC04 are characterized by a lower coefficient of
variability of the weight of the fruit than in cultivars and are more stable. Three specimens
have the largest fruit (weight) and can be used for further breeding as food cultivars. One
specimen with the most amount of seeds can be used as an oil source.
