Kinship and genetic diversity determination among six rose varieties from the Grandiflora group were carried out using ISSR thechnics. The studied varities were divided into 3 clades: I) ‘Lezginka’, ‘Queen Elizabeth’ and ‘Koralovy surpriz’ varieties; II) ‘Gurzuf’ and ‘Love’ varieties. This division into clades was confirmed by a statistical comparison of morphometric characters. On the basis of the obtained data, it can be concluded that the analysis using the selected primer group is well-suited for differentiation rose varieties into groups, which makes it possible, for one thing, to determine the genetic distance between varieties, and for another, to use these data in the future by certification of the varieties promising by resistance characters to the continental climate conditions.

The article presents the analysis of breeding work with garden roses, carried out in the Nikitsky Botanical Gardens (NBG) from 1824 to the present time. There are three main historical stages, which have different breeding tasks, as well as methods of work: the first stage is connected with the work of N.A. Hartwiss, the second stage – N.D. Kostetsky and the third one – V.N. Klimenko, Z.K. Klimenko and K.I. Zykov. The most significant breeding achievements of the NBG’s rose breeders are indicated.
