Polymorphism of quantitative traits of hellebore green (Helleborus viridis L.)

Hellebores in a number of countries are economically important ornamental crops, and these plants are also sources of glycosides used for medicinal purposes. In the literary sources, it was not possible to find information on the variability of the traits of Helleborus viridis L., and this must be known for directed plant breeding. Therefore, the aim of this work is to analyze the polymorphism of quantitative traits in hellebore green in the collection of the Tsytsin Main Botanical Garden (Moscow, Russia). Quantitative data collection was carried out in 2021. There were 20 traits, including 2 traits of plant habit, 8 traits of a leaf, 6 for a flower and 4 for a fruit. Statistical processing of the data was carried out using the calculation of the coefficients of variation and carrying out one-way analysis of variance. It was found that a high percentage of polymorphism falls on the parameters of the leaf, and a low variability - in the traits of a flower and a fruit. Features of the genotype affect the parameters of leaves by 20-30%, and no significant effect on other parameters was found.
