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; III) ‘Komsomolsky ogonek’ variety formed a separate branch.

... 'Queen Elizabeth' variety was used more likely as a parent form by 'Lezginka' variety breeding, as evidenced by the genetic distance (0.1) with a high level of statistical support 1 (> 90). Morphometric character data of studied varieties are presented in Table 2: flower diameter, petal number, peduncle length, bush height. Statistical comparison of morphometric characters using Student's t-test confirms the division of the studied varieties into 3 clade. ...Citations
The study aiming to clarify the taxonomic status of Primula mazurenkoae (Aleuritia section, Primulaceae) and determining the level of its genetic divergence in relation to the morphologically close P. farinosa was carried out. To study the genetic relationships between the closely related species, ISSR analysis was performed using five primers; 23 nucleotide sequences of nrITS region were obtained; 20 of them were revealed in the present study. Genetic analyses revealed a high level of variability in natural populations of P. mazurenkoae. Here we can conclude that the level of morphological similarity between P. mazurenkoae and P. farinosa correlates with the results of ISSR analysis and ITS nucleotide data obtained in the study.
