Abstract
Picea × albertiana ‘Conica’ is a cultivar of Alberta spruce, one of the most popular among dwarf evergreen conifers using in gardening, landscape architecture, and as Christmas trees. This cultivar was selected on the basis of mutational witch’s-brooms. The latter are shoots that appear on woody plants due to somatic mutations in buds and have anatomy and morphology differ from parent species. Sometimes a rather rare occurrence is observed on this cultivar–reversion to wild type which returns parent species phenotype partially or completely. These reversions are of particular interest because Picea × albertiana S.Br.–the parent species for cultivar ‘Conica’–has a hybrid origin. It appeared as a result of natural hybridization of Picea glauca (Moench) Voss and Picea engelmannii Parry ex Engelm. Needles anatomy from three North American species of spruce (P. × albertiana, P. glauca and P. engelmannii), cultivar P. × albertiana ‘Conica’, and revertant shoots found on it were studied. The result of research was conclusion that revertant shoots phenotype have partial match to parents species’ phenotype and to cultivars phenotype. Conclusion was made consequently was either the revertant shoots appeared as a result of suppressor mutation in buds or that there were made some taxonomic mistakes in parent species and cultivar identification.
