Essential-oil-bearing rose is one of the best known and precious essential-oil-bearing plants. The purpose of the present research was to analyze the essential-oil-bearing rose collection by the number of indicators of the main structural elements of plant (flower, leaf, shoot) to supplement the complex characteristics of specimens. This is necessary both for identifying varieties and for selection samples promising for breeding. All the studies were conducted between 2017 and 2021 under conditions of the Crimean foothills. We analyzed 50 specimens from the essential-oil-bearing rose collection, which is located at the trial fields of FSBSI “Research Institute of Agriculture of Crimea” (Krymskaya Roza village, Belogorsky district). The research was guided by the methodical recommendations, including DUS (uniformity, distinctness, stability) testing methodologies. Average number of petals in a flower in the collection was 62.1 ± 2.2 pcs. The highest degree of double-flowering was noted in 15 (30%) samples; there were more than 70 petals in the flowers of these specimens. On average for the period of four-year research, the weight of individual flowers in the collection was 3.3 ± 0.1 g (a range of variability of the indicator – from 1.6 to 5.2 g). In the collection, there were 10 (20%) samples with a flower weight of 4.0 g or more, including variety ‘Legrina’ (4.5 ± 0.2 g). Sample ‘G-168’ had the heaviest flower – 5.2 ± 0.6 g. Average flower diameter in the collection was 6.3 ± 0.1 cm (variability of this indicator ranged from 4.8 to 7.6 cm). Apical leaf dimensions: length – 5.3 ± 0.1 cm (variability from 4.3 to 6.9 cm), width – 3.1 ± 0.1 cm (from 2.0 to 4.2 cm). Anthocyanin coloration of the leaves was noted in 50% of samples; different degree of this trait on young shoots – in 38% of samples. Gradation in the collection according to the number of thorns on the shoots was also determined; weak thorn density was found in four (8%) samples, strong – in six (12%). The analysis of the collection allowed us to more ...
