In this paper, we have comparatively analyzed two subspecies of Origanum vulgare (O. vulgare ssp. hirtum and O. vulgare ssp. vulgare) in climatic conditions with higher than usual temperatures from the Institute of Genetics, Physiology and Plant Protection Chisinau, Rep. Moldova. The aim of the research was to study the producing capacity, content, composition of essential oil, as well as the polyphenols content in O. vulgare varieties, their drought testing and the selection of promising cultivars. Seven O. vulgare ssp. vulgare (Ov) varieties and fourteen O. vulgare ssp. hirtum (Oh) varieties were used as the biological material. The essential oil (EO) separated by hydrodistillation was analyzed by GC-MS techniques. The polyphenolic content was assessed using spectrophotometric techniques. The presence of a direct correlation between the content, production of essential oil and content of polyphenols has been highlighted. Thus, the varieties of O. vulgare ssp. hirtum demonstrate a higher content of essential oil than the varieties of O. vulgare ssp. vulgare, while the polyphenol content, on the other hand, is higher for the varieties of O. vulgare ssp. vulgare than for those of O. vulgare ssp. hirtum. This research has resulted in the selection of two varieties, i.e., “Savoare” of O. vulgare ssp. hirtum and “Panacea” of O. vulgare ssp. vulgare.
