The flowers of wild Rosa iberica are investigated to find the chemical constituents of its aroma and essential oil. The measurements were carried out by GC-FID and GC-MS analysis. The aromatic compositions emitted from the flowers revealed 11 constituents, among which phenyl ethanol (38.82%), benzyl alcohol (28.48%), and geraniol (12.57%) were the most abundant. The essential oil investigation detected 13 compounds, the most abundant ones being anethole (45.56%) and phthalic acid (32.23%). The scent and essential oil detected de novo in the petals of R. iberica are beneficial as natural ingredients in seasonings, therapeutic compositions, and an aromatic plant in breeding strategies of ornamental shrubs and flowers.

This study was conducted to assessthegenetic variety of 12 damask rosegenotypes of Kurdistan using morphological traits in Zaleh Research Farm affiliated to Kurdistan Province Agriculture Research Center. The experiment was carried out as a randomized complete block design with three replications and each replication included three stocks in each genotype. Results of analysis of variance showed significant differences among the studied genotypes at the probability level of 1%. Results of mean comparison showed a wide variety for studied traits in different genotypes. Relationship between traits showed that the number of flowers, plant height, average width, average length, average number of leaves, mean flower diameter, and petal to flower weight ratio per stem had positive and significant correlation at 1% probability level. Based on cluster analysis, 12 genotypes of damask rose were divided into four distinct groups according to different traits. Thus, according the results, genotypes Kurdistan 3 and Kurdistan 2 can be introduced as superior genotypes. Kurdistan 3 had high yield in flower per hectare and the number of flowers in per bush, and Kurdistan 2 had the highest flower diameter. Manuscript profile
