Comparison of selected characteristics of cultivars and wild-growing genotypes of Sambucus nigra in Slovakia

Summary/Abstract: In view of global changes, it is necessary to consider plant breeding as a process of developing new varieties and cultivars for present and future needs, with an emphasis on improving their quantitative and qualitative characteristics. The aim of this study was to compare wild-growing genotypes of elderberry (Sambucus nigra L.) with three registered cultivars Haschberg, Sambo and Bohatka in selected economic traits in Slovakia. Characters of selected genotypes and cultivars were tested in dynamics of inflorescences and fruit clusters, the morphological parameters such as the weight of fruit clusters, weight and number of drupes and weight of cluster without drupes. On the cv. Haschberg we evaluated the number of inflorescences for each individual plant for a period of three years. A high number of inflorescences was established in the first 3 years of plant growth. This is evidenced by the measurements from the 2-, 3-, 4- and 5-year old plants with the number of inflorescences on average 21.3–25.7, 42.2–51.0, 65.1–73.7 and 99.0, respectively.
