EVALUATION OF THE POSSIBILITY OF USING MOLECULAR MARKERS TO IDENTIFY GENOTYPES OF HYBRID FORMS OF RHODODENDRONS DURING IN VIVO AND IN VITRO CULTIVATION
Abstract
Formation of living collections of plants in vivo and in vitro makes it possible to preserve valuable genotypes, multiply plants, conduct a whole range of fundamental and applied research, and obtain healthy material for use in breeding work. Creation of such collections necessitates studies confirming the identity of the original specimens and regenerants obtained in aseptic culture. Such studies are of particular importance for species that are easily crossed with each other to form hybrid forms. The work shows the possibility and expediency of using nuclear and chloroplast molecular markers to identify genotypes of hybrid forms of rhododendrons during their in vivo and in vitro cultivation, with a sufficiently high degree of reliability of the results obtained, which is the most important condition for depositing plants in living collections.
