Certification of Collections of Syringa L. Varieties and It’s Significance for their Identification

Abstract

Authentication of Syringa varieties is required in all major collections. The initial information left by the originators does not make it possible to uniquely identify the varietal affiliation of the samples. In most existing descriptions of varieties, even detailed ones, subjective categories are largely used. The most interesting for the study of intraspecific and intragenital variability, molecular genetic studies, introduction and selection work, as well as for practical gardening are varieties belonging to the S. vulgaris and S. × hyacinthiflora. The aim of the study was to identify a set of constant morphological features that allow us to reliably distinguish and identify varieties of S. vulgaris and S. ×hyacinthiflora. On the basis of long-term observations of the collection of lilacs MBG RAS compiled a sample passport varieties of lilacs, which is an expanded detailed unified description. Of the selected features, 44 were the basis for "Methods of testing for distinctiveness, homogeneity and stability SYRINGA L.» No 12-06/32 from 02.08.2010, FSI State Commission of the Russian Federation for testing and protection of breeding achievements (RTG/1086/1).
