Genetic diversity analysis of Rose varieties from Grandiflora group based on ISSR molecular markers

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