Plants produce a number of volatile organic compounds (VOCs) that attract pollinators and seed bearers and enhance plant defense responses; their profile is an important tool in species identification. In addition, VOC produced by plants are used in the cosmetic, pharmaceutical, and food industries, as well as for medicinal purposes. The objective of our study was to determine how VOCs content changes with crossing. We include 3 autochthonous Slovenian rose species (R. pendulina, R. spinosissima and R. gallica) and several cultivars derived from them ('Fruhlingsmorgen', 'Fruhlingsduft', 'Maigold', 'Fruhlingsgold', 'Karl Foerster', 'Mon Amie Claire', 'Bourgogne', 'Harstad', 'Mount Everest', 'Violacea', 'Splendens', 'Complicata', and 'Charles de Mills'). The results were compared with the content of the reference plant R. damascena, known worldwide for its rich VOCs profile, and is used in the perfume industry. We checked whether the flowering time of the cultivars affected the VOCs and whether the roses included in the study were a rich source of VOCs that could potentially be used in the pharmaceutical, food, and cosmetic industries. We found that the total VOCs content varied from 2.579 µg/g FW ('Fruhlingsmorgen') to 168.24 µg/g FW ('Violacea'). In terms of total VOCs content, cultivar 'Charles de Mills' (43.12 µg/g FW) was most similar to the R. damascena (44.55 µg/g FW). We can conclude that the flowers of the roses we included in the study are a rich source of VOCs. The VOCs content in the hybrids varies depending on the purpose and objectives that the breeders wanted to achieve. With this study, we not only carefully examined the VOCs profile of the roses, but also clearly showed which compounds are present in individual taxons. In this way, it is possible to select a suitable variety or cultivar depending on the desired use, for example, for flavoring food or for a floral fragrance in the perfume industry.
