This article deals with quantitative and qualitative expressions of curly birch origins which were found in the Nízke Beskydy Mts. and then grafted and planted or sown in the Borová hora Arboretum (Slovakia). Main goals are (i) to evaluate quantitative characteristics of all individuals with the vegetative and generative origin, and (ii) to assess transfer and development of heritable traits, especially colour of bark, swirls and type of growth. We find out that quantitative characteristics are significantly influenced only by growing type (0.05, ANOVA). Transfer of qualitative characteristics on next generation is assessed through pivot tables. In contrast to the colour of the bark, hereditary transmission of swirls highly varies and it appears to be independent of the original form. Despite the high phenotypic variability and linkage of curly birch to extreme environmental factors, our results show that it is possible to grow its high-quality subsequent generations in non-original conditions.
